4-Channel A/D Converters

1 General Description

The AS1522/AS1523 are low-power, 4/2-channel, 400/

300ksps, 10-bit analog-to-digital (A/D) converters specif-

ically designed to operate with single-supply devices.

Superior AC characteristics, very low power consump-

tion, and highly-reliable packaging make these ultra-

small devices perfect for battery-powered remote-sen-

sor and data-acquisition devices.

The successive-approximation register (SAR), high-

speed sampling, high-bandwidth track/hold circuitry, and

multi-mode operation combine to make these devices

highly-flexible and configurable.

Both devices require low supply current (2.8mA @

400ksps, AS1522; 2.2mA @ 300ksps, AS1523) and fea-

ture a reduced-power mode and a power-down mode to

lower power consumption at slower throughput rates.

The devices operate from a single supply (+4.5 to +5.5V,

AS1522; +2.7 to +3.6V, AS1523). Both devices contain

an internal 2.5V reference, an integrated reference

buffer, and feature support for an external reference (1V

to V

Data accesses are made via the high-speed, 4-wire,

SPI, QSPI-, and Microwire-compatible serial interface.

The devices are available in a 16-pin TSSOP package.

tion and data-logging devices, pen-digitizers, process

control, or any other space-limited A/D application with

low power-consumption requirements.
