ADS1284IRHFR from Texas Instruments, in a WQFN-24-EP(4x5). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | DRDY | output | Active-low data ready output. |
| 2 | DOUT | output | Serial interface data output. |
| 3 | DIN | input | Serial interface data input. |
| 4 | CS | input | Serial interface chip select, active low. |
| 5 | SYNC | input | Synchronize input, rising edge active. |
| 6 | MFLAG | output | Modulator overrange flag: 0 = normal, 1 = modulator overrange. |
| 7 | DGND | power_in | Digital ground, tie to digital ground plane. |
| 8 | CAPN | passive | PGA output: connect 10-nF capacitor from CAPP to CAPN. |
| 9 | CAPP | passive | PGA output: connect 10-nF capacitor from CAPP to CAPN. |
| 10 | AINP2 | input | Positive analog input 2. |
| 11 | AINN2 | input | Negative analog input 2. |
| 12 | AINP1 | input | Positive analog input 1. |
| 13 | AINN1 | input | Negative analog input 1. |
| 14 | AVDD | power_in | Positive analog power supply, AVSS + 4.75 V to AVSS + 5.25 V recommended. |
| 15 | AVSS | power_in | Negative analog power supply, 0 V to -2.6 V relative to DGND recommended. |
| 16 | VREFN | input | Negative reference input, AVSS - 0.1 V to VREFP - 1 V. |
| 17 | VREFP | input | Positive reference input, VREFN + 1 V to AVDD + 0.1 V. |
| 18 | PWDN | input | Power-down input, active low. |
| 19 | RESET | input | Reset input, active low. |
| 20 | DVDD | power_in | Digital power supply, 1.65 V to 3.6 V recommended; if DVDD < 2.25 V, connect DVDD and BYPAS pins together. |
| 21 | DGND | power_in | Digital ground, tie to digital ground plane. |
| 22 | BYPAS | passive | 1.8-V sub-regulator output: connect 1-uF capacitor to DGND. |
| 23 | CLK | input | Master clock input (4.096 MHz), 1 to 4.096 MHz allowed. |
| 24 | SCLK | input | Serial interface shift clock input. |
| 25 | EP | passive | Thermal pad: do not electrically connect; must be soldered to PCB. |
