TLV2545 (ACTIVE)

12-Bit, 200 kSPS ADC, Ser. Out, TMS320 Compatible (up to 10MHz), Single Ch. Pseudo-Differential

 

Description

The TLV2541, TLV2542, and TLV2545 are a family of high performance, 12-bit, low power, miniature, CMOS analog-to-digital converters (ADC). The TLV254x family operates from a single 2.7-V to 5.5-V supply. Devices are available with single, dual, or single pseudo-differential inputs. Each device has a chip select (CS), serial 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 TMS320™ DSP, a frame sync signal (FS) can be used to indicate the start of a serial data frame on CS for all devices or FS for the TLV2541.

TLV2541, TLV2542, and TLV2545 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. The maximum SCLK frequency is dependent upon the mode of operation (see Table 1). The TLV254x family uses the built-in oscillator as the conversion clock, providing a 3.5-µs conversion time.
