The MAX11166 & MAX11167, industry's smallest bipolar ±5V, 16-bit ADCs graphic layout
Maxim Integrated Products has announced it is now shipping the MAX11166 & MAX11167, industry's smallest bipolar ±5V, 16-bit ADCs (analog-to-digital converters). Available in a tiny 9mm2 package, the MAX11166 and MAX11167 are the only 12-pin 16-bit bipolar ADCs to integrate an internal reference with buffer, saving cost and at least 88% board space over competing units. These highly integrated ADCs feature Beyond-the-Rails technology, which supports ±5V input signal from a single positive 5V rail. This eliminates the need for negative power supplies and simplifies designs. At 19.5mW, 500 ksps, and 1μA 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 2.5V, 3V, 3.3V, or 5V logic levels and respetively have sample rates of 500 ksps and 250 ksps. 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.
