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 emitting diode (LED) display.

Features:

• Guaranteed Zero Reading for 0 Volts Input on all Scales

• True Polarity at Zero for Precise Null Detection

• Input Current: 1pA Typ

• True Differential Input and Reference

• Direct Display Drive – No External Components Required:
