ADS7951SBRGET from Texas Instruments, in a VQFN-24-EP(4x4). 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 | +VA | power_in | Analog power supply, recommended 2.7 V to 5.25 V. |
| 2 | AGND | power_in | Analog ground. |
| 3 | MXO | output | Multiplexer output (analog output). |
| 4 | AINP | input | ADC input signal (analog input). |
| 5 | AINM | input | ADC input ground (analog input). |
| 6 | CH7 | input | Analog-input channel 7 for the multiplexer. |
| 7 | CH6 | input | Analog-input channel 6 for the multiplexer. |
| 8 | CH5 | input | Analog-input channel 5 for the multiplexer. |
| 9 | CH4 | input | Analog-input channel 4 for the multiplexer. |
| 10 | CH3 | input | Analog-input channel 3 for the multiplexer. |
| 11 | CH2 | input | Analog-input channel 2 for the multiplexer. |
| 12 | CH1 | input | Analog-input channel 1 for the multiplexer. |
| 13 | CH0 | input | Analog-input channel 0 for the multiplexer. |
| 14 | +VA | power_in | Analog power supply, recommended 2.7 V to 5.25 V. |
| 15 | AGND | power_in | Analog ground. |
| 16 | CS | input | Chip-select input pin, active low. |
| 17 | SCLK | input | Serial clock input pin, up to 20 MHz. |
| 18 | SDI | input | Serial data input pin. |
| 19 | SDO | output | Serial data output pin. |
| 20 | BDGND | power_in | Digital ground. |
| 21 | +VBD | power_in | Digital I/O supply, 1.7 V up to +VA. |
| 22 | GPIO0 | bidirectional | Programmable dual-function pin: general-purpose input or output, or active-high alarm output (configured via the Programming section). |
| 23 | REFM | input | Reference ground (analog input); a 10 µF ceramic capacitor is required between REFP and REFM. |
| 24 | REFP | input | Reference input, external 2.5 V reference (2 V to 3 V allowed); needs a clean, well-decoupled supply. |
| 25 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
