Key Features
- 12-bit successive-approximation (SAR) converter with up to 200 kSPS throughput and 10 µs conversion time per sample
- SPI-compatible 3-wire serial interface — direct connection to most MCUs without glue logic or external clocks
- Single 2.7 V to 3.6 V supply with micropower (~1 mW typical) shutdown current, ideal for battery-operated data loggers
- Differential input pair (single channel) with 0 V to VREF input range, 0.0488 % maximum integral linearity error
- 8-pin PDIP through-hole package eases hand assembly and prototyping; RoHS / Pb-free compliant
Applications
Used in low-power portable instruments, handheld test equipment, battery-monitoring boards, and educational / hobbyist microcontroller projects that need a clean 12-bit SPI ADC in DIP form factor. Also common in legacy industrial PLC analog input cards and slow-rate sensor data loggers (thermocouples, strain gauges) where 200 kSPS is more than sufficient.

Frequently Asked Questions
What is the resolution and sample rate of ADS7822P?
ADS7822P is a 12-bit SAR ADC with up to 200 kSPS conversion rate and approximately 10 µs maximum conversion time per sample. It uses a single-channel differential input pair with input range of 0 V to VREF (typically tied to the 2.7-3.6 V supply).
Is ADS7822P available in a through-hole package?
Yes, ADS7822P specifically denotes the 8-pin PDIP (Plastic Dual-In-Line) through-hole package (JESD-30 R-PDIP-T8). For surface-mount designs Texas Instruments offers ADS7822E (SOIC-8) and ADS7822U variants. The PDIP version is preferred for prototyping, repair, and educational kits.
Is ADS7822P RoHS compliant and what is the operating supply range?
Yes, ADS7822P is RoHS compliant (Pb-free Code: Yes, JESD-609 e4). The single-supply operating range is 2.7 V to 3.6 V, with micropower consumption around 1 mW during conversion and a low-power shutdown mode that drops standby current to under 1 µA, suitable for battery-powered designs.
