Maxim Integrated MAX11156
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. The MAX11156 integrates an optional internal reference and buffer, saving additional cost and space.| Part No. | MAX11156 |

GENERAL DESCRIPTION
A patented charge-pump architecture allows direct sampling of high-impedance sources. This ADC achieves 94.6dB SNR and -101.4dB THD (typ). The MAX11156 guarantees 18-bit no-missing codes and ±2.8 LSB INL (typ). 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.APPLICATIONS
