ADS1252U

Texas Instruments · Analog To Digital Converters (ADC) · SOIC-8

ADS1252U from Texas Instruments, in a SOIC-8. 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 +VIN input Positive input of the differential analog input pair, rated ±100 mA momentary / ±10 mA continuous, voltage range GND - 0.3 V to VDD + 0.3 V.
2 -VIN input Negative input of the differential analog input pair, rated ±100 mA momentary / ±10 mA continuous, voltage range GND - 0.3 V to VDD + 0.3 V.
3 +VDD power_in Single +5 V power supply input, operating range +4.75 V to +5.25 V, quiescent current 8-10 mA.
4 CLK input Device system clock input, CMOS-compatible Schmitt-trigger input, maximum 16 MHz.
5 DOUT/DRDY output Serial data output / data-ready indicator; logic LOW indicates new output word available from data output register, data shifts out on rising edge of SCLK.
6 SCLK input Serial clock input, CMOS-compatible Schmitt-trigger, independent of CLK, maximum 16 MHz; holding HIGH initiates modulator reset for converter synchronization or power-down mode.
7 GND power_in Ground / signal reference, must connect to analog ground plane per layout guidelines.
8 VREF power_in Reference voltage input, range 0.5 V to VDD, typical 4.096 V, average load current 220 µA at 16 MHz system clock.
