MAX11166 Industry's Smallest 16-Bit ADC Supports ±5V Bipolar Inputs

The MAX11166/MAX11167 16-bit, 500ksps/250ksps SAR ADCs provide excellent AC and DC performance, true bipolar input range, and small size.

The MAX11166/MAX11167 measure a ±5V input voltage range (10V PP) while operating from a single 5V supply. The patented charge pump architecture allows direct sampling of high impedance sources. The MAX11166/MAX11167 integrate an optional 5PPM/°C reference internal buffer with an external reference, which saves cost and space.

These ADCs achieve 93dB SNR and -105dB THD. The MAX11166/MAX11167 guarantee 16-bit no-miss codes and ±2 LSB (max) INL. The MAX11166/MAX11167 communicate using an SPI-compatible serial interface, 2.5V, 3V, 3.3V, or 5V logic. The serial interface can be used for daisy chaining multiple ADC parallel multi-channel applications and provides a busy indicator option to simplify system synchronization and timing. The MAX11166/MAX11167 are offered in 12-pin, 3mm x 3mm, TDFN packages. In the -40 °C to +85 °C temperature range.
