LH0032/LH0032C Ultra Fast FET
Operational Amplifier
General Description
The LH0032/LH0032C is a high slew rate, high input im-
pedance differential operational amplifier suitable for
diverse application in fast signal handling. The high al-
lowable differential input voltage, ease of output clamp-
Ing, and high output drive capability particularly suit it
for comparator applications. It may be used In applica-
tions normally reserved for video amplifiers allowing the
use of operational gain setting and frequency response
shaping into the megahertz region.
Features
• 500 V/J.lS slew rate
• 70 MHz bandwidth
• 1012Q input impedance
• 5 mV max. input offset voltage
• FET input
• Offset null with single pot
• No compensation for gains above 50
• Peak output current to 100 mA
The LH0032's wide bandwidth, high input impedance
and high output capacity make it an ideal choice for ap-
plications such as summing amplifiers in high speed D
to A's, buffers in data acquisition systems, and sample
and hold circuits. Additional applications include high
speed integrators and video amplifiers. The LH0032 is
guaranteed over the temperature range ':"55°C to +125°C
and the LH0032C is guaranteed from -25°C to+85°C.

Note 1: In order to limit maximum junction temperature to +175·C, it may be necessary to operate with Vs < ±15V when TA or Tc
exceeds specific values depending on the Po within the device package. Total Po is the sum of quiescent and load·related dissipation.
See Applications Notes AN277, "Applications of Wide·Band' Buffer Amplifiers" and AN253, "High·Speed Operational·Amplifier
Applications" for a discussion of load·related power dissipation.
Note 2: Specification is at 25·C junction temperature due to requirements of high·speed automatic testing. Actual vaiues at operating
temperature will exceed the value at TJ =25·C. When supply voltages are ±15V, no·load operating junction temperature may rise
4o-60·C above ambient and more under load conditions. Accordingly, Vos may change one to several mY, and Ie and los will change
significantly during warm·up. Refer to Ie and los vs. temperature graph for expected values.
Note 3: Measured In stili air 7 minutes after application of power.
