Analog To Digital Converters (ADC) datasheet and documents for ADS7817UG4

ADS7817UG4

Analog To Digital Converters (ADC) Overview

The ADS7817UG4 is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a high-impedance fully differential analog input and operates with a single +5V supply, consuming 2.3mW at a 200kHz sampling rate. The device supports an external reference voltage ranging from 100mV to 2.5V. It communicates via a synchronous 3-wire serial interface compatible with SPI. The component is housed in an MSOP-8 package and is rated for operation within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix 'G4' against the manufacturer's current documentation to confirm compliance status and availability. The base model ADS7817 has been identified as obsolete in some distributor records; ensure the G4 variant is actively produced or available through authorized channels before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a low-power, differential-input ADC is required for battery-powered applications. Ensure the system can provide an external reference voltage between 100mV and 2.5V, as no internal reference is present. Verify that the host microcontroller supports a 3-wire synchronous serial interface for data retrieval.

Analog To Digital Converters (ADC) Part Context

The ADS7817UG4 belongs to the ADS7817 family of micro-power sampling ADCs. It shares architectural similarities with the ADS7816 but offers differential inputs instead of single-ended. The 'U' designation indicates the SOIC/MSOP package style, while 'G4' typically denotes lead-free and RoHS-compliant manufacturing variations within the Texas Instruments portfolio.
