TLC3548 概述

The TLC3548 are 14-bit resolution high-performance, low-power, CMOS analog-to-digital converters (ADC). All TLC3548 operate from a single 5-V analog power supply and 3-V to 5-V digital supply.

The TLC3548 are designed to operate with low power consumption. The power saving feature is further enhanced with software power-down/ autopower-down modes and programmable conversion speeds. The conversion clock (internal OSC) is built in. The converter can also use an external SCLK as the conversion clock for maximum flexibility. The TLC3548 have a 4-V internal reference. The converters are specified with unipolar input range of 0-V to 5-V when a 5-V external reference is used.
