ADS7829IDRBR

Texas Instruments · Analog To Digital Converters (ADC) · SON-8-EP(3x3)

ADS7829IDRBR from Texas Instruments, in a SON-8-EP(3x3). 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 Vref power_in Reference input; the reference voltage range is 0.05 V to VCC - 0.2 V for 2.7 V ≤ VCC ≤ 3.6 V.
2 +In input Noninverting analog input; the absolute input range is -0.2 V to VCC + 0.2 V.
3 -In input Inverting analog input, to be connected to ground or to a remote ground sense point; the absolute input range is -0.2 V to 1.0 V.
4 GND power_in Ground reference for the device.
5 CS/SHDN input Chip select when LOW and shutdown mode when HIGH.
6 DOUT output Serial output carrying a 12-bit data word that is valid on the falling edge of DCLOCK; the serial output is enabled by the second clock pulse after the falling edge of CS, followed by one null bit and then 12 data edges.
7 DCLOCK input Data clock that synchronizes the serial data transfer and determines the conversion speed.
8 +VCC power_in Power supply; operating range is 2.7 V to 3.6 V, with reduced performance down to 2.0 V and operation to 5.25 V stated in the electrical specifications.
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
