TLV2541 概述

The TLV2541 are high performance, 12-bit, low power, miniature, CMOS analog-to-digital converters (ADC). The TLV2541 operates from a single 2.7-V to 5.5-V supply.

The TLV2541 are designed to operate with very low power consumption. The power saving feature is further enhanced with an autopower-down mode. The TLV2541 features a high-speed serial link to modern host processors with SCLK up to 20 MHz. The maximum SCLK frequency is dependent upon the mode of operation. The TLV2541 uses the built-in oscillator as the conversion clock, providing a 3.5-µs conversion time.
