MAX5430CEKA+

Overview

The MAX5430CEKA+ is a digitally programmable precision voltage divider designed for programmable gain amplifiers (PGAs). It operates with dual supplies up to ±15V and features four parallel taps. The device utilizes a serial interface for control and is housed in an 8-pin SOT-23 package. It supports an operating temperature range from -40°C to +85°C.

Feature Summary

• ±15V Digitally Programmable Precision Voltage Dividers
• Four Parallel Taps for Flexible Gain Control
• SOT-23-8 Surface-Mount Package

Applications

• Programmable Gain Amplifier (PGA) Biasing
• Precision Voltage Reference Adjustment
• Instrumentation Signal Conditioning

Procurement Notes

Verify the suffix '+T' or absence thereof against the specific datasheet revision, as packaging formats vary between tape-and-reel and cut tape. Confirm RoHS compliance status directly with Analog Devices documentation, as historical data indicates mixed compliance records for this part number across different distributors.

Selection Notes

Select the MAX5430CEKA+ when precise, digitally adjustable voltage division is required for PGA circuits within a compact SOT-23 footprint. Ensure the design accommodates the ±15V supply requirement and serial communication protocol. Verify thermal performance within the -40°C to +85°C industrial range.

Part Context

This component belongs to the MAX5430 family of precision voltage dividers. It serves as a digital alternative to mechanical potentiometers in high-precision analog signal paths, offering non-volatile memory options in related variants but requiring verification for this specific CEKA+ designation regarding memory retention capabilities.

Replacement Considerations

Cross-reference with MAX5430AEKA+ for potential pin-compatible alternatives. Verify electrical specifications and package dimensions before substitution, as manufacturer revisions may alter internal circuitry or tolerance levels.
