Integrated Circuit
Air Core Meter Driver
Description:
The NTE1670 is a function generator/driver for air–core (moving–magnet) meter movements in a
14–Lead DIP type package. A Norton amplifier and an NPN transistor are included on chip for signal
conditioning as required. Driver outputs are self–centering and develop ± 4.5V swing at 20mA. Better
than 2% linearity is guaranteed over a full 305–degree operating range.

D Self–Centering 20mA Outputs
D 12V Operation
D Norton Amplifier
D Function Generator
Applications:
D Air–Core Meter Driver
D Tachometers
D Ruggedized Instruments

Note 1 For operation above +25°C, the NTE1670 must be derated based upon a +125°C maximum
junction temperature and a thermal resistance of +76°C/W which applies for the device sol-
dered in a printed circuit board and operating in a still–air ambient.
