16-Bit, 135ksps, Single-Supply ADCs with
Bipolar Analog Input Range
General Description
The MAX1178/MAX1188 16-bit, low-power, successive-
approximation analog-to-digital converters (ADCs) fea-
ture automatic power-down, a factory-trimmed internal
clock, and a byte-wide parallel interface. The devices
operate from a single +4.75V to +5.25V analog supply
and feature a separate digital supply input for direct
interface with a +2.7V to +5.25V digital logic.
The MAX1188 accepts a bipolar analog input voltage
range of ±10V, while the MAX1178 accepts a bipolar
analog input voltage range of ±5V. All devices consume
no more than 26.5mW at a sampling rate of 135ksps
when using an external reference, and 31mW when using
the internal +4.096V reference. AutoShutdown™ reduces
supply current to 0.4mA at 10ksps.
The MAX1178/MAX1188 are ideal for high-perfor-
mance, battery-powered, data-acquisition applications.
Excellent AC performance (THD = -100dB) and DC
accuracy (±2 LSB INL) make the MAX1178/MAX1188
ideal for industrial process control, instrumentation, and
medical applications.
The MAX1178/MAX1188 are available in a 20-pin
TSSOP package and are fully specified over the -40°C
to +85°C extended temperature range and the 0°C to
+70°C commercial temperature range.
