MAX11158 - 18-Bit, 500ksps, ±5V SAR ADC with Internal Reference in µMAX - 数据转换器和采样-保持电路 - Small, True Bipolar Input, 18-Bit SAR ADC with Internal Reference - 美信半导体

产品概述

The MAX11158 is an 18-bit, 500ksps, SAR ADC offering excellent AC and DC performance with true bipolar input range, internal reference, and small size. The MAX11158 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 MAX11158 integrates a low drift reference with internal buffer, saving the cost and space of an external reference.

This ADC achieves 93.7dB SNR and -100.0dB THD. The MAX11158 guarantees 18-bit no-missing codes and ±2.7 LSB INL (typ).

The MAX11158 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 for multichannel applications and provides a busy indicator option for simplified system synchronization and timing.

The MAX11158 is offered in a 10-pin, 3mm x 5mm, μMAX® package and is specified over the -40°C to +85°C temperature range.
