TECHNICAL NOTES

1. The use of good high-frequency circuit board layout techniques is

required for rated performance. The extensive use of a ground plane

for all common connections is recommended. Lead lengths should be

kept to a minimum with point-to-point connections wired directly to the

amplifier pins. 1μF tantalum bypass capacitors should be used at the

±15V supply pins.

2. Operation of the AM-1435MM and MM-QL over the +85 to +125°C

temperature range requires additional thermal dissipation to achieve

rated performance. Use of an

18°C/W heat sink is recommended.

3. No input protection is provided so as to maximize frequency response.

As a result, several precautions must be observed. Do not apply the

positive supply voltage before the negative supply. Do not apply signals

to either input prior to power-up. If frequency response is not critical,

installation of an external input-protection circuit is recommended.

4. A 1μF bypass capacitor (C4) connected from OPTIONAL BYPASS

CAPACITOR (pin 1) to COMMON (pin 14) may be required to inhibit

output oscillation when driving capacitive loads.

5. To ensure stable operation when the noise gain is less than 10, a 2pF

compensation capacitor (C1) must be connected between pins 3 and 7.

The value of the compensation capacitor may be application sensitive.

6. The AM-1435 is a prime choice as a current-to-voltage converter due

currents are easily compensated by adding a resistor from pin 8 to

ground, which is equal to the parallel combination of the feedback

resistor and input impedance.
