TLV1544I.

The TLV1544I is CMOS 10-bit switched-capacitor successive-approcimation analog-to-digital converter.It has an on-chip 11-channel multiplexer that can select any one of eight analog inputs or any one of three internal self-test voltages.

Features of the TLV1544I are:(1)10-bit-resoultion ADC;(2)wide range single-supply operation of 2.7V dc to 5.5V dc;(3)built-in analog multiplexer with 8 analog input channels;(4)end-of-conversion flag;(5)inherent sample-and-hold function;(6)built-in self-test modes;(7)programmable power and conversion rate;(8)hardware I/O clock phase aujust input.

The absolute maximum ratings of the TLV1544I can be summarized as:(1)supply voltage range:-0.5V to 6.5V;(2)input voltage range:-0.3V to VCC+0.3V;(3)output voltage range:-0.3V to VCC+0.3V;(4)positive reference voltage:VCC+0.1V;(5)negative reference voltage:-0.1V;(6)peak input current:±20mA;(7)operating free-air temperature range:-55 to 125;(8)storage temperature range:-65 to 150;(9)lead temperature 1.6mm from the case for 10 seconds:260;(10)peak total input current:-30mA.
