AS1536/AS1537

12-Bit, Single Supply, Low-Power, 73ksps A/D Con-

verters

1 General Description

2 Key Features

ꢀ

12-Bit Resolution with 7.5µs Conversion Time

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.

Sampling Rate: 73ksps

Straight Binary (Unipolar) Data Format

Single-Supply Operation:+2.7V to +5.25V

Internal 2.5V Reference (AS1536)

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.

Low Power-Consumption:

- 4mW (73ksps, AS1536)

- 3mW (73ksps, AS1537)

- 66µW (1ksps, AS1537)

- 1µW (Shutdown Mode)

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.

ꢀ

Integrated Track/Hold Amplifier

Internal Clock

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.

SPI/QSPI/Microwire 3-Wire Serial Interface

Operating Temperature Range: -40 to +85ºC

8-pin SOIC-150 Package

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.

3 Applications

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

tion, data logging devices, lab instruments, or for any

other space-limited A/D devices with low power con-

sumption and single-supply requirements.

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

package.
