ADS7822EB

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

ADS7822EB from Texas Instruments, in a MSOP-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 VREF power_in Reference input; the external reference can be any voltage from 50mV to VCC and directly sets the analog input range.
2 +In input Noninverting pseudo-differential analog input that should remain within GND - 200mV to VCC + 200mV to maintain converter linearity.
3 -In input Inverting input, connected to ground or a remote ground sense point, which should not drop below GND - 200mV or exceed GND + 1V.
4 GND power_in Ground pin, which should be placed on a clean ground point kept away from the microprocessor or DSP ground connection.
5 CS/SHDN input Chip select when low and shutdown mode when high; a new conversion starts only when CS is taken high and then returned low.
6 DOUT output Serial output carrying the 12-bit conversion result MSB first, with data valid on the falling edge of DCLOCK and a CMOS swing from 0V to VCC.
7 DCLOCK input Data clock that synchronizes the serial data transfer and determines conversion speed, with an external clock range of 10kHz to 3.2MHz.
8 +VCC power_in Power supply, operating over a range of 2.0V to 5.25V, with specified performance at 2.7V to 3.6V and 4.75V to 5.25V.
