HA17080 General 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.

HA17080 Maximum Ratings

Item Symbol Ratings (P, PS Series) Unit Notes
Power-supply voltage VCC +18 V  
     VEE                         18     V  
Differential input voltage Vin(diff) ±30 V  
Input voltage Vin ±15 V 1
Allowable power dissipation PT 625 mW 2
Operating temperature Topr 20 to +75 °C  
Storage temperature Tstg 55 to +125 °C  
Notes: 1. When the power-supply voltage is less than ±15 V, the input voltage must fall within the powersupply voltage range.
2. These are the allowable values up to Ta = 50°C for the P and PS series. Derate by 8.3 mW/°C above that temperature.

HA17080 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
`  High slew rate: 13 V/s
`  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.
(CL < 100 pF: voltage follower mode)
