# 4-Channel Audio Filtering Board ## Description ALERT: This is a test board to quickly verify the process of idea to gerber in Flux. I guarantee it doesn't work and many of the circuits are wrong, not to mention poorly designed. Don't copy them. ## Project Details - **Owner:** chaykak2 - **Created:** 5/31/2022 - **Last Updated:** 7/25/2024 - **Visibility:** Public - **Forks:** 1 ## Key Components ### IC2 — [AD5697RBCPZ-RL7](https://www.flux.ai/vasyl/ad5697rbcpz-rl7~jsd.md) - Manufacturer Part Number: AD5697RBCPZ-RL7 - Part Type: Integrated Circuit - Datasheet URL: https://www.analog.com/media/en/technical-documentation/data-sheets/AD5697R.pdf - Manufacturer Name: Analog Devices Inc. **Pins:** - ~LDAC - ~RESET - A0 - A1 - GAIN - GND - GND - NC - NC - RSTSEL - SCL - SDA - VDD - VLOGIC - VOUTA - VOUTB - VREF ### IC3 — [AD5697RBCPZ-RL7](https://www.flux.ai/vasyl/ad5697rbcpz-rl7~jsd.md) - Manufacturer Part Number: AD5697RBCPZ-RL7 - Part Type: Integrated Circuit - Datasheet URL: https://www.analog.com/media/en/technical-documentation/data-sheets/AD5697R.pdf - Manufacturer Name: Analog Devices Inc. **Pins:** - ~LDAC - ~RESET - A0 - A1 - GAIN - GND - GND - NC - NC - RSTSEL - SCL - SDA - VDD - VLOGIC - VOUTA - VOUTB - VREF ### IC4 — [TPS62056DGS](https://www.flux.ai/vasyl/tps62056dgs~q9.md) - Part Type: Integrated Circuit - Manufacturer Part Number: TPS62056DGS - Datasheet URL: https://www.ti.com/general/docs/suppproductinfo.tsp?distId=10&gotoUrl=http%253A%252F%252Fwww.ti.com%252Flit%252Fgpn%252Ftps62050 - Manufacturer Name: Texas Instruments **Pins:** - EN - FB - GND - LBI - LBO - PG - PGND - SW - SYNC - VIN ### J10 — [USB micro](https://www.flux.ai/jharwinbarrozo/usb-micro-b~t8p.md) - Manufacturer Part Number: USB3140-30-0170-0-C - Manufacturer Name: GCT **Pins:** - D- - D+ - GND - ID - VBUS ### J10 — [AUDIO JACK 3.5mm](https://www.flux.ai/adrian95/audio-jack-35mm~yqh.md) - Part Type: Connector **Pins:** - ~ - ~ - GND - L - R ### J12 — [AUDIO JACK 3.5mm](https://www.flux.ai/adrian95/audio-jack-35mm~yqh.md) - Part Type: Connector **Pins:** - ~ - ~ - GND - L - R ### J5 — [AUDIO JACK 3.5mm](https://www.flux.ai/adrian95/audio-jack-35mm~yqh.md) - Part Type: Connector **Pins:** - ~ - ~ - GND - L - R ### J6 — [AUDIO JACK 3.5mm](https://www.flux.ai/adrian95/audio-jack-35mm~yqh.md) - Part Type: Connector **Pins:** - ~ - ~ - GND - L - R ### J7 — [AUDIO JACK 3.5mm](https://www.flux.ai/adrian95/audio-jack-35mm~yqh.md) - Part Type: Connector **Pins:** - ~ - ~ - GND - L - R ### J8 — [AUDIO JACK 3.5mm](https://www.flux.ai/adrian95/audio-jack-35mm~yqh.md) - Part Type: Connector **Pins:** - ~ - ~ - GND - L - R ### J8 — [AUDIO JACK 3.5mm](https://www.flux.ai/adrian95/audio-jack-35mm~yqh.md) - Part Type: Connector **Pins:** - ~ - ~ - GND - L - R ### J9 — [AUDIO JACK 3.5mm](https://www.flux.ai/adrian95/audio-jack-35mm~yqh.md) - Part Type: Connector **Pins:** - ~ - ~ - GND - L - R ### U1 — [OPA1679IDR](https://www.flux.ai/jecstronic/opa1679idr~ebg.md) - Part Type: Operational Amplifier (OP-AMP) - Datasheet URL: https://www.ti.com/general/docs/suppproductinfo.tsp?distId=10&gotoUrl=https%3A%2F%2Fwww.ti.com%2Flit%2Fgpn%2Fopa1679 - Manufacturer Name: Texas Instruments - Manufacturer Part Number: OPA1679IDR **Pins:** - -IN A - -IN B - -IN C - -IN D - +IN A - +IN B - +IN C - +IN D - OUT A - OUT B - OUT C - OUT D - V- - V+ ### U2 — [STM32F030C6T6](https://www.flux.ai/vasy_skral/stm32f030c6t6~l0l.md) - Manufacturer Part Number: STM32F030C6T6 - Manufacturer Name: STMicroelectronics - Part Type: Microcontroller - Datasheet URL: https://www.st.com/content/ccc/resource/technical/document/datasheet/a4/5d/0b/0e/87/c4/4d/71/DM00088500.pdf/files/DM00088500.pdf/jcr:content/translations/en.DM00088500.pdf **Pins:** - BOOT0 - NRST - PA0 - PA1 - PA10 - PA11 - PA12 - PA13 - PA14 - PA15 - PA2 - PA3 - PA4 - PA5 - PA6 - PA7 - PA8 - PA9 - PB0 - PB1 - PB10 - PB11 - PB12 - PB13 - PB14 - PB15 - PB2 - PB3 - PB4 - PB5 - PB6 - PB7 - PB8 - PB9 - PC13 - PC14 - PC15 - PF0 - PF1 - PF6 - PF7 - VDD - VDD - VDD - VDDA - VSS - VSS - VSSA *The full schematic, PCB layout, bill of materials, and interactive design are available at [https://www.flux.ai/chaykak2/4-channel-audio-filtering-board~dl](https://www.flux.ai/chaykak2/4-channel-audio-filtering-board~dl).* --- *Generated from [https://www.flux.ai/chaykak2/4-channel-audio-filtering-board~dl](https://www.flux.ai/chaykak2/4-channel-audio-filtering-board~dl)*
