HA-5101
10MHz, Low Noise, Operational Amplifiers
The HA-5101 is a dielectrically isolated operational amplifier
featuring low noise, (3.0nV/
Hz at 1kHz).
DC characteristics of the HA-5101 assure accurate
performance. The 0.5mV offset voltage is externally adjust-
able and offset voltage drift is just 3
V/
o
C. An offset current
of only 30nA reduces input current errors and an open loop
voltage gain of 1 x 10
6
V/V increases loop gain for low
distortion amplification.
The HA-5101 is ideal for audio applications, especially low-
level signal amplifiers such as microphone, tape head and
phono cartridge preamplifiers. Additionally, it is well suited
for low distortion oscillators, low noise function generators
and high Q filters.

Application Information
Operation At
5V Supply
The HA-5101 performs well at V
S
=
5V exhibiting typical
characteristics as listed below:
Offset Adjustment
The following is the recommended V
IO
adjust configuration:
NOTE: Proper decoupling is always recommended, 0.1
F high quality
capacitor should be at or very near the device's supply pins.
Input Protection
The HA-5101 has built-in back-to-back protection diodes
which will limit the differential input voltage to approximately
Ch. 1 = 2.5V/Div.
Timebase = 1.00
s/Div.
FIGURE 3. LARGE SIGNAL TRANSIENT RESPONSE
Ch. 1 = 50mV/Div.
Timebase = 100ns/Div.
FIGURE 4. SMALL SIGNAL TRANSIENT RESPONSE
NOTES:
8. A
V
= -1.
9. Feedback and summing resistors should be 0.1% matched.
10. Clipping diodes are optional, HP5082-2810 recommended.

may be exceeded, then current limiting resistors must be
used. No more than 25mA should be allowed to flow in the
HA-5101's input.

Such That:
Output Saturation
When an op amp is overdriven, output devices can saturate
and sometimes take a long time to recover. Saturation can
be avoided (sometimes) by using circuits such as:
If saturation cannot be avoided the HA-5101 recovers from a
25% overdrive in about 6.5
