MAXIM Integrated Products, represented by Arrow Electronics , has introduced a new family of 16-/14-bit ADCs with an analogue input voltage range of 0 to 10V, ±5V, or ±10V.

This ADC family includes the MAX1156-MAX1159, MAX1174/MAX1175, MAX1177/MAX1178/MAX1179, and MAX1187/MAX1188/MAX1189.

These ADCs connect directly to microcontrollers and DSPs through an 8-bit or 16-bit-wide parallel interface. Excellent ac performance (THD = -100dB) and dc accuracy (±1LSB INL) make them ideal for industrial process control, instrumentation, and medical applications.

This family of ADCs operates from a single +5V supply and features a separate DVDD pin, which allows for direct interfacing to 2.7V to 5.25V digital logic.

Low-power operation consumes only 23mW at the maximum conversion rate of 135ksps. Automatic shutdown between conversions reduces operating current to 0.4mA at 10ksps. An internal 4.096V or external reference determines the full-scale analogue input range.

The 16-bit-wide parallel interface devices are available in a 28-pin TSSOP package. The 8-bit wide parallel interface devices are available in a 20-pin TSSOP package.

Both packages are available in the extended (-40°C to +85°C) and commercial (0°C to +70°C) temperature ranges.
