ICL7136CM44ZT集成電路（IC）的ADC/DAC-特殊用途規(guī)格書PDF中文資料

The Intersil ICL7136 is a high performance, low power 31/2

digit, A/D converter. Included are seven segment decoders,

display drivers, a reference, and a clock. The ICL7136 is

designed to interface with a liquid crystal display (LCD) and

includes a multiplexed backplane drive.

The ICL7136 brings together a combination of high

accuracy, versatility, and true economy. It features auto-zero

to less than 10μV, zero drift of less than 1μV/oC, input bias

current of 10pA (Max), and rollover error of less than one

count. True differential inputs and reference are useful in all

systems, but give the designer an uncommon advantage

when measuring load cells, strain gauges and other bridge

type transducers. Finally, the true economy of single power

supply operation, enables a high performance panel meter

to be built with the addition of only 10 passive components

and a display.

The ICL7136 is an improved version of the ICL7126,

eliminating the overrange hangover and hysteresis effects,

and should be used in its place in all applications. It can also

be used as a plug-in replacement for the ICL7106 in a wide

variety of applications, changing only the passive

components.
