EVALUATION KIT AVAILABLE MAX11156 18-Bit, 500ksps, ±5V SAR ADC with Internal Reference in TDFN Features General Description The MAX11156 18-bit, 500ksps, SAR ADC offers excellent AC and DC performance with true bipolar input range, small size, and internal reference. The MAX11156 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 MAX11156 integrates an optional 6ppm/°C reference with internal buffer, saving the cost and space of an external reference. The MAX11156 produces 94.6dB SNR and -105dB THD (typ). The MAX11156 guarantees 18-bit no-missing codes. The MAX11156 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 MAX11156 is offered in a 12-pin, 3mm x 3mm, TDFN package and is specified over the -40°C to +85°C temperature range.
