AD632BD

Overview

The AD632BD is a monolithic four-quadrant multiplier and divider manufactured by Analog Devices Inc. It features internally trimmed precision with a maximum multiplying error of ±0.5% at +25°C. The device operates within a temperature range of -25°C to +85°C and utilizes a 14-lead Side-Brazed Ceramic Dual In-Line Package (D-14). Key electrical specifications include a small signal bandwidth of 1 MHz, a slew rate of 20 V/µs, and a settling time of 2 µs. It supports supply voltages from ±8 V to ±18 V with a quiescent current of 6 mA.

Feature Summary

• Internally trimmed for high accuracy with a maximum multiplying error of ±0.5% at +25°C.
• Supports differential inputs for X, Y, and Z channels with high impedance characteristics.
• Capable of variable gain applications with scale factors adjustable up to ×10.
• Features low noise design with wideband noise of 90 µV rms in the 10 Hz to 10 kHz range.

Applications

• High quality analog signal processing
• Differential ratio and percentage computations
• Algebraic and trigonometric function synthesis
• Accurate voltage controlled oscillators and filters

Procurement Notes

Verify the specific suffix 'BD' indicates the B-grade performance variant with ±0.5% error and D-package format. Confirm RoHS compliance status as standard parts may differ from 'Z' suffixed versions. Ensure the operating environment stays within the specified -25°C to +85°C range to maintain guaranteed accuracy levels.

Selection Notes

Select the AD632BD when a maximum multiplying error of ±0.5% is required without external trimming. Choose this model over the AD632AD if tighter error tolerances are necessary. Consider the D-14 package for through-hole mounting requirements. Verify that the application does not require extended temperature operation beyond +85°C, which would necessitate the S or T series.

Part Context

The AD632BD belongs to the AD632 family of precision analog multipliers. It serves as an improved successor to the industry-standard AD532, offering pin-for-pin compatibility alongside enhanced specifications. The device integrates thin-film resistors and a buried zener reference to ensure stability and accuracy under adverse conditions.

Replacement Considerations

The AD632AD is a compatible alternative within the same family but offers a wider maximum multiplying error of ±1.0%. For extended temperature ranges (-55°C to +125°C), consider the AD632SD or AD632TD variants. Direct replacement requires verifying package compatibility and thermal management requirements.
