16-Bit, 135ksps, Single-Supply ADCs with Bipolar Analog Input Range
General Description
The MAX1178/MAX1188 16-bit, low-power, successiveapproximation analog-to-digital converters (ADCs) feature 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.
