__________________General Description
The MAX1242/MAX1243 are low-power, 10-bit analog-
to-digital converters (ADCs) available in 8-pin pack-
ages. They operate with a single +2.7V to +5.25V
supply and feature a 7.5s successive-approximation
ADC, a fast track/hold (1.5s), an on-chip clock, and a
high-speed, 3-wire serial interface.
Power consumption is only 3mW (VDD = 3V) at the
73ksps maximum sampling speed. A 2A shutdown
mode reduces power at slower throughput rates.
The MAX1242 has an internal 2.5V reference, while the
MAX1243 requires an external reference. The MAX1243
accepts signals from 0V to VREF, and the reference
input range includes the positive supply rail. An exter-
nal clock accesses data from the 3-wire interface,
which connects directly to standard microcontroller I/O
ports. The interface is compatible with SPI, QSPI, and
MICROWIRE.
Excellent AC characteristics and very low power com-
bined with ease of use and small package size make
these converters ideal for remote-sensor and data-
acquisition applications, or for other circuits with
demanding power consumption and space require-
ments. The MAX1242/MAX1243 are available in 8-pin
PDIP and SO packages.
