ADC122S625

Dual 12-Bit, 50 kSPS to 200 kSPS, Simultaneous Sampling

A/D Converter

General Description

Features

The ADC122S625 is a dual 12-bit, 50 kSPS to 200 kSPS si-

multaneous sampling Analog-to-Digital (A/D) converter. The

analog inputs on both channels are sampled simultaneously

to preserve their relative phase information to each other. The

converter is based on a successive-approximation register

architecture where the differential nature of the analog inputs

is maintained from the internal track-and-hold circuits

throughout the A/D converter to provide excellent common-

mode signal rejection. The ADC122S625 features an external

reference that can be varied from 1.0V to V_A.

Guaranteed performance from 50 kSPS to 200 kSPS

External Reference

Wide Input Common-Mode Voltage Range

Single High-Speed Serial Data Output

Operating Temperature Range of −40°C to +105°C

SPI™/QSPI™/MICROWIRE™/DSP compatible Serial

Interface

The ADC122S625's serial data output is binary 2's comple-

ment and is compatible with several standards, such as

SPI™, QSPI™, MICROWIRE™, and many common DSP se-

rial interfaces. The serial clock (SCLK) and chip select bar

(CS) are shared by both channels.

Operating from a single 5V analog supply and a reference

voltage of 2.5V, the total power consumption while operating

at 200 kSPS is typically 8.6 mW. With the ADC122S625 op-

erating in power-down mode, the power consumption re-

duces to 2.6 µW. The differential input, low power consump-

tion, and small size make the ADC122S625 ideal for direct

connection to sensors in motor control applications.
