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:
   NTE2050 (LED)
   NTE2051 (LCD)
• Low Noise – Less than 15µVP–P
• On–Chip Clock and Reference
• Low Power Dissipation – Typically Less than 10mW
• No Additional Active Circuits Required
