TLC2551 Datasheet (Texas Instruments) - SERIAL ANALOG-TO-DIGITAL CONVERTERS

TLC2551, SERIAL ANALOG-TO-DIGITAL CONVERTERS

The TLC2551, TLC2552, and TLC2555 are a family of high performance, 12-bit, low-power, miniature, CMOS analog-to-digital converters (ADC).

The TLC255x family uses a 5-V supply.

Devices are available with single, dual, or single pseudo-differential inputs.

Each device has a chip select (CS), serial

TLC2551 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 TLC255x family uses SCLK as the conversion clock, which provides synchronous operation and a minimum conversion time of 1.5 µs using a 20-M
