1 General Description

The AS1536/AS1537 are low-power, 12-bit, 73ksps ana-

log-to-digital (A/D) converters specifically designed for

single-supply A/D applications. Superior AC characteris-

tics, very low power consumption, and robust packaging

make these ultra-small devices perfect for battery-pow-

ered analog-data collection devices.

The integrated successive-approximation register (SAR)

and a fast (1.5µs) sampling track/hold time provide an

economic and highly-reliable A/D conversion solution.

The AS1536/AS1537 operate from a single 2.7V to

5.25V supply. The AS1537 requires an external refer-

ence, using less power than the AS1536, however, the

AS1536 features an internal 2.5V reference.

As with the AS1537, the AS1536 can also be used with

an external reference, which uses the input range 0V to

VREF, including the positive supply range.

The AS1537 consumes only 3mW (VDD = 3V) at the

73ksps maximum sampling speed. Both devices feature

a low-current (0.3µA) shutdown mode, which reduces

power consumption at slower throughput rates.

Data accesses are made via the standard, high-speed

3-wire serial interface, which is SPI-, QSPI-, and

Microwire-compatible. Both devices contain an internal

clock, however, both devices also support an external

clock for increased flexibility.

The AS1536/AS1537 are available in an 8-pin SOIC-150

package.
