Analog Devices / Maxim Integrated MAX11156 18-bit, 500ksps SAR ADC
Analog Devices MAX11156 18-bit, 500ksps SAR ADC is a small true bipolar +/-5V, 18-bit analog-to-digital converter. MAX11156 offers excellent AC and DC performance with true bipolar input range, small size, and internal reference. The device 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. MAX11156 integrates an optional 6ppm/°C reference with internal buffer, saving the cost and space of an external reference. MAX11156 produces 94.6dB SNR and -105dB THD (typ).
The Analog Devices MAX11156 18-bit, 500ksps SAR ADC guarantees 18-bit no-missing codes. It 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.
