# ADC0804LCN/NOPB Engineering Specifications **General Description** The ADC0804LCN/NOPB is a CMOS successive-approximation analog-to-digital converter manufactured by Texas Instruments. It converts a differential analog input signal into an eight-bit digital output and is designed for direct connection to microprocessors through a parallel data interface. The device uses a differential potentiometric-ladder architecture to improve common-mode rejection and allow the analog zero-input level to be offset. Its adjustable reference input permits smaller analog voltage spans to use the converter’s full resolution. Tri-state output latches allow direct connection to a processor data bus without additional interface logic. The converter can operate as a microprocessor-controlled device or as a standalone, free-running converter. An integrated clock generator allows operation using an external resistor-capacitor network, although an external clock signal may also be used. **Engineering Specifications** **Manufacturer:** Texas Instruments **Manufacturer Part Number:** ADC0804LCN/NOPB **Component Type:** Analog-to-Digital Converter **Converter Architecture:** Successive Approximation Register **Resolution:** Eight bits **Number of Channels:** One **Input Configuration:** Differential analog input **Analog Input Range:** Zero volts to five volts with a five-volt supply **Supply Voltage Range:** Four and one-half volts to six and three-tenths volts **Typical Supply Voltage:** Five volts **Reference Type:** External, supply-based or ratiometric reference **Reference Input:** Adjustable VREF divided-by-two input **Digital Interface:** Eight-bit parallel interface **Microprocessor Compatibility:** Directly compatible with common eight-bit microprocessors **Conversion Time:** Approximately one hundred microseconds **Maximum Sampling Rate:** Approximately ten kilosamples per second **Total Unadjusted Error:** Plus or minus one least significant bit **Digital Outputs:** Latched tri-state outputs **Logic Compatibility:** TTL and MOS-compatible inputs and outputs **Clock Configuration:** Integrated clock generator with external resistor-capacitor timing or external clock input **Operating Modes:** Processor-controlled, standalone or continuous free-running operation **Operating Temperature Range:** Zero degrees Celsius to seventy degrees Celsius **Package Type:** Twenty-pin plastic dual in-line package **Mounting Style:** Through-hole mounting **Package Width:** Standard three-tenths-inch DIP format **Environmental Classification:** Lead-free and RoHS-compliant NOPB version **Lifecycle Status:** Obsolete and generally not recommended for new production designs **Typical Applications** Suitable for sensor signal conversion, temperature-monitoring systems, voltage measurement, transducer interfaces, embedded control systems, laboratory equipment, educational electronics projects and general-purpose data-acquisition circuits. #ADC0804LCN #ADC0804 #TexasInstruments #AnalogToDigitalConverter #ADC #DataAcquisition #EmbeddedSystems #ElectronicsEngineering #IntegratedCircuit #MicrocontrollerProjects #ElectronicComponents 8 Bit Analog to Digital Converter 1 Input 1 SAR 20-PDIP https://mm.digikey.com/Volume0/opasdata/d220001/medias/docus/721/ADC080x.pdf

Accelerometer X, Y, Z Axis ±2g, 4g, 8g, 16g 0.05Hz ~ 1.6kHz 14-LGA (3x5) The ADXL345-EP is an extended performance version of the ADXL345, which is a small, thin, ultralow power, 3-axis accelerometer with high resolution (13-bit) measurement at up to ±16 g. Digital output data is formatted as 16-bit twos complement and is accessible through either a SPI (3- or 4-wire) or I2 C digital interface. The ADXL345-EP is well suited for extended temperature range industrial and aerospace equipment. It measures the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock. Its high resolution (3.9 mg/LSB) enables measurement of inclination changes less than 1.0°. Several special sensing functions are provided. Activity and inactivity sensing detect the presence or lack of motion by comparing the acceleration on any axis with user-set thresholds. Tap sensing detects single and double taps in any direction. Freefall sensing detects if the device is falling. These functions can be mapped individually to either of two interrupt output pins. An integrated memory management system with a 32-level first in, first out (FIFO) buffer can be used to store data to minimize host processor activity and lower overall system power consumption. Low power modes enable intelligent motion-based power management with threshold sensing and active acceleration measurement at extremely low power dissipation. The ADXL345-EP is supplied in a small, thin, 3 mm × 5 mm × 1 mm, 14-lead, enhanced plastic package. Ultralow power: as low as 23 µA in measurement mode and 0.1 µA in standby mode at VS = 2.5 V (typical) Power consumption scales automatically with bandwidth User-selectable resolution from 10 to 13 bits 4 mg/LSB scale factor in all g ranges 32-sample FIFO minimizes host processor load Single tap, double tap, and free-fall detection Activity/inactivity monitoring Supply voltage range: 2.0 V to 3.6 V I/O voltage range: 1.7 V to VS SPI (3- and 4-wire) and I2C digital interfaces Flexible interrupt modes mappable to either interrupt pin Measurement ranges selectable via serial command Bandwidth selectable via serial command 10,000 g shock survival Pb free/RoHS compliant Small and thin: 3 mm × 5 mm × 1 mm LGA package #CommonPartsLibrary #Sensor #Motion-sensor #accelerometer
