説明

EE-Sim^®を使って設計とシミュレーションを行う:

The MAX1156/MAX1158/MAX1174 14-bit, low-power, successive-approximation 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 +2.7V to +5.25V digital logic.

The MAX1156 accepts a 0 to +10V analog input voltage range. The MAX1158 accepts a ±10V bipolar analog input voltage range, while the MAX1174 accepts a ±5V bipolar analog input voltage range. 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 (typ) at 10ksps.

The MAX1156/MAX1158/MAX1174 are ideal for high-performance, battery-powered, data-acquisition applications. Excellent AC performance (THD = -100dB) and DC accuracy (±1 LSB INL) make the MAX1156/ MAX1158/MAX1174 ideal for industrial process control, instrumentation, and medical applications.

The MAX1156/MAX1158/MAX1174 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.
