NTE889M
Integrated Circuit
Dual, Low Power, JFET OP Amplifier
Description:
The NTE889M is a JFET–input operational amplifier in an 8–Lead DIP type package designed for low
power applications and features high input impedance, low input bias current, and low input offset
current. Advanced design techniques allow for higher slew rates, gain bandwidth products, and output swing.
Features:
D Low Supply Current: 200µA/Amplifier
D Low Input Bias Current: 5pA
D High Gain Bandwidth: 2MHz
D High Slew rate: 6V/µs
D High Input Impedance: 1012Ω
D Large Output Voltage Swing: ±14V
D Output Short Circuit Protection

Note 1. Differential voltages are at the non–inverting input terminal with respect to the inverting input
terminal.
Note 2. The magnitude of the input voltage must never exceed the magnitude of the supply voltage
or 15V, whchever is less.
Note 3. Power dissipation must be considered to ensure maximun junction temperature (TJ) is not
exceeded.
