Product Brief

AS1534

12-bit, 8-Channel, Low-Power, 200ksps A/D Converter

1 General Description

2 Key Features

ꢀ Sampling Rate: 200ksps

ꢀ 8- and 16-Bit Parallel Interface

ꢀ Analog Input Types:

The AS1534 is a low-power, 8-channel, 200ksps, 12-bit

analog-to-digital (A/D) converter specifically designed to

operate with single-supply devices. Superior AC charac-

teristics, very low power-consumption, and highly-reli-

able packaging make the AS1534 perfect for battery-

powered remote-sensor and data-acquisition devices.

- 8-Channel Single-Ended

- 4-Channel Pseudo-Differential

- 4-Channel Fully-Differential

The successive-approximation register (SAR), high-

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

configurable inputs combine to make the AS1534 highly-

flexible and configurable.

ꢀ Software-Configurable Unipolar or Bipolar Inputs

ꢀ Internal +2.5V Reference

Internal registers are used to control the AS1534 fea-

tures, report on the status of the device, and hold the

A/D conversion results.

ꢀ External Reference: 1.2V to VDD

ꢀ Low-Power Operation:

The device requires very low supply-current at the

200ksps max sampling speed, and features flexible

power-down modes to reduce power consumption at

slower throughput rate.

- 7.5mW (VDD = 3 V)

- 1.5mW (Using Automatic Power-Down after Con-

version; VDD = 3 V, 10ksps)

ꢀ Single-Supply Operation: +3 to +3.6V

ꢀ 44-pin PQFP Package

The AS1534 operates from a single +3 to +3.6V supply

and contains an internal 2.5V reference and integrated

reference buffer. The device also supports an external

reference.

Data accesses are made via the fast 8-/16-bit parallel

interface in support of a wide range of microprocessors.

3 Applications

The device is ideal for remote sensors, data-acquisition

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

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

power-consumption requirements.

The AS1534 is available in a 44-pin PQFP package.
