LM2202M

Overview

The LM2202M is a dual operational amplifier manufactured by National Semiconductor, now part of Texas Instruments. It features a low supply current and high slew rate, making it suitable for battery-powered applications. The device operates within a wide voltage range and offers rail-to-rail input and output capabilities. Key electrical parameters include a supply voltage range of 3V to 32V, a quiescent current of 150µA per amplifier, and a slew rate of 0.5V/µs. The input offset voltage is typically 2mV, with a bandwidth of 1MHz. It is housed in an 8-pin SOIC package.

Procurement Notes

Verify the manufacturer status as National Semiconductor was acquired by Texas Instruments. Ensure the component is sourced from authorized distributors to guarantee authenticity. Check for updated datasheets reflecting TI specifications. Confirm package type and temperature range requirements match your design needs. Validate RoHS compliance if required for your region.

Selection Notes

Consider the LM2202M for designs requiring low power consumption with moderate speed. Its rail-to-rail I/O simplifies interface with single-supply systems. Compare performance against newer TI alternatives for improved specifications. Evaluate thermal management requirements based on load conditions. Verify availability and lead times through official channels.

Part Context

The LM2202M belongs to the LM2202 series of dual operational amplifiers. It is designed for general-purpose analog signal processing tasks. The device is part of National Semiconductor's portfolio before its acquisition by Texas Instruments. It shares similarities with other low-power op-amps in terms of functionality but offers specific performance characteristics suited for portable electronics.

Replacement Considerations

Check for direct replacements such as the TL072 or LM358 depending on performance requirements. Consult Texas Instruments documentation for recommended upgrades. Ensure pin compatibility and electrical specifications match the original design constraints.
