MAX1178

19-2755; Rev 1; 8/03 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. AutoShutdown™ reduces supply current to 0.4mA at 10ksps. The MAX1178/MAX1188 are ideal for high-performance, 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. o Byte-Wide Parallel Interface o Analog Input Voltage Range: ±10V, ±5V o Single +4.75V to +5.25V Analog Supply Voltage o Interface with +2.7V to +5.25V Digital Logic o ±2 LSB INL o ±1 LSB DNL o Low Supply Current...
