description (continued)
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 TLV2548 and TLV2544 are designed to operate with very low
power consumption. The power-saving feature is further enhanced with software/hardware/autopower-down
modes and programmable conversion speeds. The conversion clock (OSC) and reference are built-in. The
converter can use the external SCLK as the source of the conversion clock to achieve higher (up to 2.8
s when
a 20 MHz SCLK is used) conversion speed. Two different internal reference voltages are available. An optional
external reference can also be used to achieve maximum flexibility.
The TLV2544Q and the TLV2548Q are characterized for operation from 40
°C to 125°C. The TLV2548M is
characterized for operation from 55
°C to 125°C.
