ADS7951SBRGET

Texas Instruments · Analog To Digital Converters (ADC) · VQFN-24-EP(4x4)

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).
