MAX11166：16-Bit, 500ksps, ±5V SAR ADC with Internal Reference in TDFN

Industry's Smallest, True Bipolar ±5V, 16-Bit ADCs

The MAX11166 16-bit, 500ksps, SAR ADC offers excellent AC and DC performance with true bipolar input range, small size, and internal reference. The MAX11166 measures a ±5V (10VP-P) input range while operating from a single 5V supply. A patented charge-pump architecture allows direct sampling of high-impedance sources. The MAX11166 integrates an optional internal reference and buffer, saving additional cost and space. These ADCs achieve 92.9dB SNR and -103dB THD. The MAX11166 guarantees 16-bit no-missing codes and ±0.4 LSB INL (typ). The MAX11166 communicates using an SPI-compatible serial interface at 2.5V, 3V, 3.3V, or 5V logic. The serial interface can be used to daisy-chain multiple ADCs in parallel for multichannel applications and provides a busy indicator option for simplified system synchronization and timing. The MAX11166 is offered in 12-pin, 3mm x 3mm, TDFN package and is specified over the -40°C to +85°C temperature range.
