Revision 1.02
1 - 29
The AS1530/AS1531 are low-power,8/4-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.
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.
Both devices require low supply current (2.8mA @
400ksps, AS1530; 2.2mA @ 300ksps, AS1531) and fea-
ture a reduced-power mode and a power-down mode to
lower power consumption at slower throughput rates.
The devices operate from a single supply (+4.5 to +5.5V,
AS1530; +2.7 to +3.6V, AS1531). Both devices contain
an internal 2.5V reference, an integrated reference
buffer, and feature support for an external reference (1V
to V
DD
).
Data accesses are made via the high-speed, 4-wire,
SPI, QSPI-, and Microwire-compatible serial interface.
The devices are available in a 20-pin TSSOP package.
