MAX1392, MAX1395 1.5V to 3.6V, 357ksps, 1-Channel True-Differential/2-Channel Single-Ended, 10-Bit, SAR ADCs

Description

The MAX1392/MAX1395 micropower, serial-output, 10-bit, analog-to-digital converters (ADCs) operate with a single power supply from +1.5V to +3.6V. These ADCs feature automatic shutdown, fast wake-up, and a high-speed 3-wire interface. Power consumption is only 0.740mW (V_DD = +1.5V) at the maximum conversion rate of 357ksps. AutoShutdown™ between conversions reduces power consumption at slower throughput rates.

The MAX1392/MAX1395 require an external reference V_REF that has a wide range from 0.6V to V_DD. The MAX1392 provides one true-differential analog input that accepts signals ranging from 0 to V_REF (unipolar mode) or ±V_REF/2 (bipolar mode). The MAX1395 provides two single-ended inputs that accept signals ranging from 0 to V_REF. Analog conversion results are available through a 5MHz, 3-wire SPI™-/QSPI™-/MICROWIRE™-/digital signal processor (DSP)-compatible serial interface. Excellent dynamic performance, low voltage, low power, ease of use, and small package sizes make these converters ideal for portable battery-powered data-acquisition applications, and for other applications that demand low power consumption and minimal space.

The MAX1392/MAX1395 are available in a space-saving (3mm x 3mm) 10-pin TDFN package. The parts operate over the extended (-40°C to +85°C) and military (-55°C to +125°C) temperature ranges.
