description
The TLC1518 and TLC1514 are a family of high-performance, 10-bit, low power, 1.4
s, CMOS SAR
analog-to-digital converters (ADC) which operate from a single 5 V power supply. These devices have three
digital inputs and a 3-state output [chip select (CS), serial input-output clock (SCLK), serial data input (SDI), and
serial data output (SDO)] that provide a direct 4-wire interface to the serial port of most popular host
microprocessors (SPI interface). When interfaced with a DSP, a frame sync (FS) signal is used to indicate the
start of a serial data frame.
In addition to a high-speed A/D converter and versatile control capability, these devices have an on-chip analog
multiplexer that can select any analog inputs or one of three internal self-test voltages. The sample-and-hold
function is automatically started after the fourth SCLK edge (normal sampling) or can be controlled by a special
pin, CSTART, to extend the sampling period (extended sampling). The normal sampling period can also be
programmed as short (12 SCLKs) or as long (24 SCLKs) to accommodate faster SCLK operation popular
among high-performance signal processors. The TLC1518 and TLC1514 are designed to operate with very low
power consumption. The power-saving feature is further enhanced with software/hardware/auto power down
modes and programmable conversion speeds. The converter uses the external SCLK as the source of the
conversion clock. There is a 4-V internal reference available and an optional external reference can also be used
to achieve maximum flexibility.
