The MAX11166 and MAX11167 are the industry's smallest bipolar ±5 V, 16-bit analog-to-digital converters (ADCs). They are available in a tiny 12-pin, 3 mm x 3 mm (9 mm2) TDFN package, and are specified over the -40°C to +85°C temperature range. The MAX11166 and MAX11167 are the only 12-pin, 16-bit bipolar ADCs to integrate an internal reference buffer, saving cost and at least 88% board space over competing solutions. These highly integrated ADCs feature Beyond-the-Rails™ technology, and measure a ±5 V (10 VP-P) input range while operating from a single 5 V supply. This technology eliminates the need for negative power supplies and simplifies designs. At 19.5 mW, 500 ksps, and 1 µA in shutdown mode, the ADCs are applicable for precision-measurement data acquisition systems (DASs), industrial/process control, medical instrumentation, and automatic test equipment (ATE).

The MAX11166 and MAX11167 communicate using an SPI-compatible serial interface at 2.5 V, 3 V, 3.3 V, or 5 V logic levels, and have sample rates of 500 ksps and 250 ksps, respectively. The serial interface can be used to daisy-chain multiple ADCs for multichannel simultaneous-sampling applications. It also provides a "busy" indicator option for simplified system synchronization and timing. Maxim's proprietary input-charge-pump architecture allows direct sampling of high-impedance sources, eliminating the need for external analog buffers to drive the ADC inputs in some applications.
