ADS8325IDGKR

Texas Instruments · Analog To Digital Converters (ADCs) · MSOP-8

ADS8325IDGKR from Texas Instruments, in a MSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 REF input Reference input. Sets the ADC full-scale range; accepts 2.5V to VDD+0.3V. Reference input current ~1mA typical during conversion; ~0.1uA when CS=VDD (shutdown).
2 +IN input Noninverting analog input of the differential input pair. Full-scale range is +IN - (-IN) = 0 to VREF. Operating common-mode range -0.3V to 0.5V.
3 -IN input Inverting analog input of the differential input pair. Typically tied to analog ground; allowed range -0.3V to 0.5V.
4 GND power_in Ground return for both analog and digital supply. All voltages are referenced to this pin.
5 CS/SHDN input Active-low chip select; when held high the device enters shutdown mode (IDD ~0.1uA typ at VDD=3V). Falling edge starts a conversion; timing is referenced to CS falling to DCLOCK edges.
6 DOUT tri_state Serial data output (MSB-first, straight binary). Tri-stated when CS is high. Data valid ~15ns typ after DCLOCK falling edge.
7 DCLOCK input External data clock input; synchronizes serial data transfer and sets the conversion speed. Clock frequency 0.024 to 2.4MHz; a minimum of 22 clocks required for a full 16-bit conversion.
8 +VDD power_in Positive supply input, 2.7V to 5.5V. Operating supply current ~0.75mA typ at 3V, ~0.9mA at 5V; ~0.1uA typ in power-down.
