description

The TLV2541/2542/2545 are a family of high performance, 12-bit, low power, miniature 3.6

µs, CMOS

analog-to-digital converters (ADC). The TLV254x family operates from a single 2.7 V to 5.5 V. Devices are

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 TLV2542/45 have a shared CS/FS terminal.

TLV2541/2/5 are designed to operate with very low power consumption. The power saving feature is further

enhanced with an autopower-down mode. This product family features a high-speed serial link to modern host

processors with SCLK up to 20 MHz. TLV254x family uses the built in oscillator as conversion clock, providing

a 3.6

µs conversion time.
