Product Brief

AS1532, AS1533

12-Bit, Single-Supply, Low-Power, 400/300ksps,

4-Channel A/D Converters

1 General Description

2 Key Features

ꢀ Single-Supply Operation:

- +4.5 to +5.5V (AS1532)

- +2.7 to +3.6V (AS1533)

The AS1532/AS1533 are low-power, 4/2-channel, 400/

300ksps, 12-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.

ꢀ Sampling Rate:

- 400ksps (AS1532)

- 300ksps (AS1533)

ꢀ Software-Configurable Analog Input Types:

- 4-Channel Single-Ended

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.

- 4-Channel Pseudo Differential Referenced to COM

- 2-Channel Pseudo Differential

- 2-Channel Fully Differential

Both devices require low supply current (2.8mA @

400ksps, AS1532; 2.2mA @ 300ksps, AS1533) and fea-

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

lower power consumption at slower throughput rates.

ꢀ Software-Configurable Input Range

ꢀ Internal +2.5V Reference

ꢀ Low-Current Operation:

- 2.8mA @ 400ksps (AS1532)

- 2.2mA @ 300ksps (AS1533)

- 0.4mA in Reduced-Power Mode

- 0.5µA in Full Power-Down Mode

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

AS1532; +2.7 to +3.6V, AS1533). Both devices contain

an internal 2.5V reference, an integrated reference

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

to VDD).

ꢀ SPI/QSPI/Microwire/TMS320-Compatible

ꢀ 16-pin TSSOP Package

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.

3 Applications

The devices are ideal for remote sensors, data-acquisi-

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

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

low power-consumption requirements.
