ADS7959SRGER 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, specified from 2.7 V to 5.25 V (3.3 V nominal) with respect to AGND. |
| 2 | AGND | power_in | Analog ground for the device. |
| 3 | MXO | output | Multiplexer output pin, an analog output of the channel multiplexer. |
| 4 | AINP | input | ADC input signal; AINP or CHn to AGND must stay between -0.3 V and VA + 0.3 V (absolute maximum ratings). |
| 5 | AINM | input | ADC input ground, the negative analog input reference node for the converter. |
| 6 | Ch7 | input | Analog input channel for the multiplexer; AINP or CHn to AGND must stay between -0.3 V and VA + 0.3 V. |
| 7 | Ch6 | input | Analog input channel for the multiplexer; AINP or CHn to AGND must stay between -0.3 V and VA + 0.3 V. |
| 8 | Ch5 | input | Analog input channel for the multiplexer; AINP or CHn to AGND must stay between -0.3 V and VA + 0.3 V. |
| 9 | Ch4 | input | Analog input channel for the multiplexer; AINP or CHn to AGND must stay between -0.3 V and VA + 0.3 V. |
| 10 | Ch3 | input | Analog input channel for the multiplexer; AINP or CHn to AGND must stay between -0.3 V and VA + 0.3 V. |
| 11 | Ch2 | input | Analog input channel for the multiplexer; AINP or CHn to AGND must stay between -0.3 V and VA + 0.3 V. |
| 12 | Ch1 | input | Analog input channel for the multiplexer; AINP or CHn to AGND must stay between -0.3 V and VA + 0.3 V. |
| 13 | Ch0 | input | Analog input channel for the multiplexer; AINP or CHn to AGND must stay between -0.3 V and VA + 0.3 V. |
| 14 | +VA | power_in | Analog power supply, specified from 2.7 V to 5.25 V (3.3 V nominal) with respect to AGND. |
| 15 | AGND | power_in | Analog ground for the device. |
| 16 | CS | input | Chip-select input pin, active low; the input signal is sampled on the falling edge of CS. |
| 17 | SCLK | input | Serial clock input pin; SCLK frequency is specified up to 20 MHz. |
| 18 | SDI | input | Serial data input pin. |
| 19 | SDO | output | Serial data output pin. |
| 20 | BDGND | power_in | Digital ground for the digital I/O supply domain. |
| 21 | +VBD | power_in | Digital I/O supply, specified from 1.7 V to +VA. |
| 22 | GPIO0 | bidirectional | General-purpose input or output; on this device it is the active-high Alarm output (configured in the Programming section). |
| 23 | REFM | input | Reference ground input; a 10-µF ceramic decoupling capacitor is required between REFP and REFM. |
| 24 | REFP | input | Reference input; the device is specified for an external 2.5-V ±10-mV reference, with recommended reference voltage of 2 V to 3 V. |
| 25 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
