5962-9211701MPA

Overview

The AD827 is a dual high-speed, low-power operational amplifier manufactured by Analog Devices Inc. It provides a 50 MHz unity-gain bandwidth and a 300 V/µs slew rate while consuming only 10 mA total supply current. The device features a maximum input offset voltage of 2 mV and an input voltage noise density of 15 nV/√Hz. It operates from ±4.5 V to ±18 V supplies and can drive unlimited capacitive loads with a short-circuit current limit of 32 mA.

Feature Summary

• High-speed performance with 50 MHz unity-gain bandwidth and 300 V/µs slew rate
• Low power consumption with 10 mA total supply current for both amplifiers
• Capable of driving unlimited capacitive loads without stability issues
• Excellent video performance with minimal differential gain and phase errors

Applications

• Video line drivers for terminated or unterminated cables
• Input buffers for 8-bit to 10-bit A/D converters
• Output amplifiers for high-speed D/A converters
• Multistage active filters requiring wide bandwidth

Procurement Notes

Verify the specific package option (N-8, Q-8, R-16, or E-20A) and temperature range (J, A, or S) required for your design. Confirm that the MIL-STD-883B processing requirements are met if using military-grade variants. Ensure proper bypassing with 0.1 µF ceramic capacitors near the supply pins to maintain stability and performance in high-frequency applications.

Selection Notes

Select this component when high speed and low power are critical constraints. It is suitable for applications requiring significant capacitive loading or precise video signal transmission. Consider the available packages based on board space and thermal dissipation needs. Verify that the operating temperature range aligns with your system environment requirements.

Part Context

This part number corresponds to the AD827 series, a dual version of the industry-standard AD847 op amp. It is designed to offer high-speed, low-power performance at a low cost. The device is available in various packages including plastic mini-DIP, cerdip, SOIC, and LCC, catering to different manufacturing and environmental needs.

Replacement Considerations

The AD847 is the single-channel counterpart to this dual amplifier. Other high-speed op amps may be considered if pin compatibility is not required, but direct replacement should verify bandwidth, slew rate, and power consumption specifications.
