Description

The PA16 and PA16A are wideband, high output current operational amplifiers designed for driving resistive, inductive, and capacitive loads. They feature a complementary "collector output" stage that swings close to the supply rails and is protected against inductive kickback. The output stage is biased for class A/B operation for optimal linearity. The amplifiers are internally compensated but not recommended for use as unity gain followers. Continuous operation under load requires mounting on a properly rated heatsink.

Specifications
  • Supply Voltage: ±38V
  • Output Current: 5A within SOA
  • Power Dissipation: 62.5W
  • Input Voltage Differential: ±30V
  • Operating Temperature Range: -40°C to 85°C
Absolute Maximum Ratings

These ratings include supply voltage, output current, power dissipation, input voltage, and temperature limits. Exceeding these limits may result in reduced product life.

Typical Application

The PA16 is suitable for vehicular sound system power stages, utilizing its low internal loss and low distortion for a clear audio amplifier. The circuit uses AC coupling to minimize DC voltage across the speaker, with current limit resistors for protection against output short circuits.

Safe Operating Area (SOA)

The SOA curves illustrate the limits for the power operational amplifier. For reactive and EMF generating loads, the current limits should be set appropriately to ensure safe operation.

Device Mounting

The case is electrically isolated and should be mounted directly to a heatsink with thermal compound. Proper mounting ensures reliable operation and minimizes thermal resistance.

PA16-1

Power Operational Amplifiers FEATURES The PA16 and PA16A are wideband, high output current operational amplifiers designed to drive resistive, inductive and capacitive loads. Their complementary “collector output” stage can swing close to the supply rails and is protected against inductive kickback. For optimum linearity, the output stage is biased for class A/B operation. The safe operating area (SOA) can be observed for all operating conditions by selection of user programmable, current limiting resistors (down to 10mA). Both amplifiers are internally compensated but are not recommended for use as unity gain followers. For continuous operation under load, mounting on a heatsink of proper rating is recommended. These hybrid integrated circuits utilize thick film (cermet) resistors, ceramic capacitors and semiconductor chips to maximize reliability, minimize size and give top performance. Ultrasonically bonded aluminum wires provide reliable interconnections at all operating temperatures. The Power SIP package is electrically isolated. ♦ HIGH POWER BANDWIDTH — 350kHz ♦ HIGH SLEW RATE — 20V/μs ♦ FAST SETTLING TIME — 600ns ♦ LOW CROSSOVER DISTORTION — Class A/B ♦ LOW INTERNAL LOSSES — 1.2V at 2A ♦ HIGH OUTPUT CURRENT — ±5A PEAK ♦ LOW INPUT BIAS CURRENT — FET Input ♦ ISOLATED CASE — 300 VDC ♦ MOTOR, VALVE AND ACTUATOR CONTROL ♦ MAGNETIC DEFLECTION CIRCUITS UP TO 5A ♦ POWER TRANSDUCERS UP TO 350 kHz ♦ AUDIO AMPLIFIERS UP TO 44W RMS Copyright © Apex Microtechnology, Inc. 2
