AD632BDZ

Overview

The AD632BDZ is an internally trimmed, monolithic four-quadrant analog multiplier and divider manufactured by Analog Devices. It operates within a temperature range of -25°C to +85°C and supports dual power supplies from ±8V to ±18V. The device features a small-signal bandwidth of 1 MHz, a slew rate of 20 V/µs, and settling time of 2 µs. It provides a maximum multiplying error of ±0.5% at +25°C and wideband noise of 90 µV rms (10 Hz to 10 kHz). Packaged in a 14-lead Side-Brazed Dual In-Line Package (SBDIP), it includes high-impedance differential inputs for X, Y, and Z channels.

Feature Summary

• Internally trimmed precision architecture ensuring low total multiplying error without external adjustments.
• High-impedance differential inputs for all signal channels (X, Y, and Z) to facilitate flexible circuit configurations.
• Integrated stable reference and bias circuits that maintain accuracy under varying supply conditions.
• Capable of functioning as a variable gain amplifier with high common-mode rejection.

Applications

• High quality analog signal processing
• Differential ratio and percentage computations
• Algebraic and trigonometric function synthesis

Procurement Notes

Verify the specific ordering suffix 'BDZ' corresponds to the 14-lead SBDIP package variant when sourcing. Confirm RoHS compliance status associated with the 'Z' suffix. Ensure the procurement channel sources directly from authorized distributors or the manufacturer to guarantee component authenticity and traceability.

Selection Notes

Select this model for applications requiring a pretrimmed ±0.5% error multiplier in a through-hole package. It serves as a pin-compatible upgrade to the industry standard AD532 with improved specifications. Consider the 1 MHz bandwidth and ±18V supply limits when designing signal conditioning stages.

Part Context

This component belongs to the AD632 family of precision analog multipliers. The 'B' designation indicates a tighter error tolerance compared to the 'A' series. The 'DZ' suffix specifies the 14-lead ceramic DIP package with RoHS compliance. This part is designed for general-purpose analog computation tasks requiring high stability.

Replacement Considerations

The AD632BDZ is pin-for-pin compatible with the AD532. Other variants within the AD632 family, such as AD632ADZ or AD632AHZ, share the same footprint but differ in error specifications or package type.

FAQ

How does the AD632BDZ compare to the AD532?

The AD632BDZ is pin-for-pin compatible with the AD532 but offers improved specifications, including fully differential high-impedance Z inputs and lower multiplying errors.

What is the maximum multiplying error for the AD632BDZ?

The AD632BDZ has a guaranteed maximum multiplying error of ±0.5% at +25°C without external trims.
