HA4-2420/883

Instrumentation, Op Amps, Buffer Amps Overview

The HA4-2420/883 is a sample and hold amplifier manufactured by Harris Corporation, housed in a 20-CLCC package. It features one circuit with a slew rate of 3.5V/µs. The device operates within a supply voltage range of 10V to 36V minimum and maximum, respectively. It draws 5mA of supply current and provides an output current of 15 mA per channel. The input bias current is 130 nA, and the input offset voltage is 2.5 mV. The gain-bandwidth product is 8 MHz. It functions reliably across a temperature range of -55°C to 125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify RoHS non-compliance status prior to integration into environmentally regulated assemblies. Confirm the 20-CLCC package dimensions match the target PCB footprint. Ensure thermal management strategies accommodate the specified operating temperature range of -55°C to 125°C. Validate that the 10V to 36V supply requirements align with the system power architecture.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a dedicated sample and hold amplifier is required rather than a general-purpose operational amplifier. Consider the 20-CLCC surface-mount package constraints during layout design. Evaluate the 3.5V/µs slew rate against the maximum input signal frequency to prevent distortion. Verify compatibility with the system's voltage rails given the 10V minimum supply requirement.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the Harris Corporation HA4 series of high-performance linear integrated circuits. The /883 suffix typically denotes military-grade qualification or specific packaging variations within the company's portfolio. These amplifiers are designed for demanding applications requiring precision and reliability in harsh environments.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct substitutes may include other Harris/Harman sample and hold amplifiers in similar packages. Cross-reference pinouts and electrical specifications carefully. Generic op-amps cannot replace the specific sample and hold functionality without external circuitry modifications.
