J-FET Input Operational Amplifiers
Description
Since J-FET input operational amplifiers are formed from a pair of J-FET transistors, they provide
superlative characteristics, including a high input impedance and a low input bias current. Thus they can be
used in a wide range of applications, from general-purpose control equipment to medical applications. In
particular, they are optimal for processing signals from high-impedance sensors.
Hitachi J-FET input operational amplifiers are available in single, dual, and quad versions. Other than the
HA17080, all products are internal phase compensation types and include a built-in phase compensation
capacitor. The HA17080 and the HA17083 allow offset adjustment. These products are also available in
“A” grade versions with superlative electrical characteristics to allow the selection of an operational
amplifier appropriate for the application.
Features
• Wide operating power supply voltage range: ±5 V to ±18 V
• Low input bias current: 30 pA
• Low input offset current: 5 pA
• High input impedance: 1012 Ω
• High slew rate: 13 V/µs
• Wide common mode input voltage range with operation possible near the power-supply voltage (VCC).
• High voltage gain: 106 dB
• The HA17080 and HA17083 support offset adjustment.
• Pin compatible with the Texas Instruments TL080 series.
Notes: 1. Since these products are high input impedance operational amplifiers, contamination may cause
the input bias and input offset currents to increase if they are handled with bare hands.
Avoid contamination when handling these devices.
2. Since these products provide a high slew rate, oscillation may occur due to load capacitances.

Notes: 1. The non-A ratings apply to the HA17080, HA17082, HA17083, and HA17084.
The A version ratings apply to the HA17080A, HA17082A, HA17083A, and HA17084A.
2. This is the J-FET gate leakage current, which is temperature dependent. The junction
temperature must be held near room temperature when measuring this parameter.
