Product Summary

The TLV2545ID is a high performance, 12-bit, low power, miniature 3.6 ms, CMOS analog-to-digital converter (ADC). The TLV2545ID operates from a single 2.7 V to 5.5 V. The device is available with single, dual, or single pseudo-differential inputs. The TLV2541 has a 3-state output chip select (CS), serial output clock (SCLK), and serial data output (SDO) that provides a direct 3-wire interface to the serial port of most popular host microprocessors (SPI interface). When interfaced with a DSP, a frame sync signal (FS) is used to indicate the start of a serial data frame. The TLV2545ID has a shared CS/FS terminal.
