NTE2050 & NTE2051

Integrated Circuit

3¹/₂–Digit Single Chip A/D Converter

Description:

The NTE2050 and NTE2051 are high performance, low power 3–1/2 digit A/D converters containing

all the necessary active devices on a single CMOS IC. Included are seven segment decoders, display

drivers, reference and a clock. The NTE2051 is designed to interface with a liquid crystal display

(LCD) and includes a backplane drive; the NTE2050 will directly drive an instrument–size light emit-

ting diode (LED) display.

The NTE2050 and NTE2051 bring together an unprecedented combination of high accuracy, versatil-

ity, and true economy. High accuracy like auto–zero to less than 10µV, zero drift of less than 1µV/°C,

input bias current of 10pA max., and roll–over error of less than one count. The versatility of true differ-

ential input and reference is useful in all systems, but gives the designer an uncommon advantage

when measuring load cells, strain gauges and other bridge–type transducers. And, finally, the true

economy of single power supply operation (NTE2051), enabling a high performance panel meter to

be built with the addition of only 7 passive components and a display.

Features:

D Guaranteed Zero Reading for 0 Volts Input on all Scales

D True Polarity at Zero for Precise Null Detection

D Input Current: 1pA Typ

D True Differential Input and Reference

D Direct Display Drive – No External Components Required:

NTE2050 (LED)

NTE2051 (LCD)

D Low Noise – Less than 15µV_P–P

D On–Chip Clock and Reference

D Low Power Dissipation – Typically Less than 10mW

D No Additional Active Circuits Required
