MAX412CPA

Instrumentation, Op Amps, Buffer Amps Overview

The MAX412CPA is a dual precision operational amplifier from the MAX410/MAX412/MAX414 family, manufactured by Analog Devices Inc./Maxim Integrated. It features a unity-gain bandwidth of 28MHz and a slew rate of 4.5V/µs. The device guarantees an input voltage-noise density of less than 2.4nV/√Hz at 1kHz and operates with a supply current of 2.5mA per amplifier. It supports low-voltage operation ranging from ±2.4V to ±5V and offers an output voltage swing of 7.3V peak-to-peak into a 2kΩ load from ±5V supplies. The component is housed in an 8-pin Plastic DIP package and functions within a temperature range of 0°C to +70°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'CPA' confirms the 8-pin Plastic DIP package and the commercial temperature range of 0°C to +70°C. Confirm that the manufacturer designation matches Analog Devices Inc./Maxim Integrated. Ensure the component meets RoHS compliance standards as indicated by the datasheet documentation. Cross-reference the ordering information table to validate availability status and exact part identification before procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when designing systems requiring low-noise precision amplification under low-voltage constraints. The dual configuration allows for cost-effective implementation in multi-channel signal paths. Consider the 8-pin DIP package for through-hole prototyping or legacy board designs. Evaluate the 28MHz bandwidth against system frequency requirements to ensure adequate phase margin and stability without excessive power consumption.

Instrumentation, Op Amps, Buffer Amps Part Context

The MAX412CPA belongs to the MAX410/MAX412/MAX414 series of single/dual/quad op amps designed for high-speed, low-voltage systems. This family sets a standard for noise performance by combining low noise with efficient power consumption. The MAX412 specifically provides two independent amplifiers in one package, sharing the same electrical characteristics and pinout compatibility as the single (MAX410) and quad (MAX414) variants within the series.
