Product Brief

AS1524/AS1525

Micro-Power, 12-Bit, 150ksps, ADC, Single Ended

or Differential

1 General Description

2 Key Features

ꢀ

Single-Supply Operation: +2.7 to +5.25V

The AS1524/AS1525 are low-power, 12-bit analog-to-

digital converters (ADCs) designed to operate with a sin-

gle +2.7 to +5.25V supply. Excellent dynamic perfor-

mance, low power consumption, and simplicity make

these devices perfect for portable battery-powered data-

acquisition applications.

Automatic Shutdown Between Conversions

Low Power Consumption

- 350µA @ 150ksps

The devices are available as the standard products

listed in Table 1.

- 245µA @ 100ksps

- 24µA @ 10ksps

Table 1. Standard Products

- 2.5µA @ 1ksps

0 to VREF

The devices feature a successive-approximation regis-

ter (SAR), automatic shutdown, fast wakeup (1.4µs),

and low-power consumption at the maximum sampling

rate of 150ksps.

ꢀ

Input Common Mode Range from GND to VDD

3-Wire SPI-/QSPI-/MICROWIRE-Compatible Serial

Interface

Automatic shutdown (0.2µA) between conversions

results in reduced power consumption (at slower

throughput rates).

ꢀ

Internal Conversion Clock

8-pin TDFN (3x3mm) Package

Data access are made via an external clock through the

SPI-/QSPI-/MICROWIRE-compatible 3-wire high-speed

serial interface.

3 Applications

The AS1525/AS1524 are available in a 8-pin TDFN

(3x3mm) package.

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.
