ADR3540WARMZ-R7

Overview

The ADR3540WARMZ-R7 is a micropower, high-precision CMOS voltage reference with a nominal output of 4.096 V. It operates within an input voltage range of 4.3 V to 5.5 V and supports a maximum sourcing current of 10 mA and sinking current of -3 mA. The device features an initial output voltage error of ±0.1% and a temperature coefficient of 8 ppm/°C for the A grade. Quiescent current is 100 μA maximum in normal operation. It includes an enable pin, low dropout voltage of 250 mV at 2 mA, and output noise of 29 μV p-p (0.1 Hz to 10 Hz). Qualified for automotive applications, it functions from -40°C to +125°C.

Feature Summary

Utilizes proprietary DigiTrim technology for digital trimming of initial accuracy and temperature coefficient during final assembly.
Features low long-term drift and low output voltage hysteresis to improve lifetime system accuracy.
Includes an enable pin that allows shutdown mode with reduced quiescent current.
Designed with precision layout techniques to minimize thermal hysteresis and solder heat resistance drift.

Applications

Automotive battery monitors
Portable instrumentation
Process transmitters
Remote sensors
Medical instrumentation

Procurement Notes

Verify the specific grade suffix 'A' in the part number corresponds to the required 8 ppm/°C temperature coefficient specification. Confirm the 'RM-8' package designation matches the MSOP-8 footprint requirements. Ensure the '-R7' suffix aligns with reel packaging needs. Cross-reference the automotive qualification status if operating in harsh environments.

Selection Notes

Select this component when a stable 4.096 V reference is needed with moderate power consumption. The A grade offers a balance between cost and performance compared to the B grade. Consider the 4-wire Kelvin connection capability for high-accuracy applications requiring precise load regulation. Evaluate the 10 mA sourcing capability against the application's peak load demands.

Part Context

This device belongs to the ADR35xx family of micropower voltage references, which includes models with outputs ranging from 2.5 V to 5.0 V. All members share similar architectural benefits, including low noise and high precision. The ADR3540 specifically targets applications requiring a standard 4.096 V level, often used in ADC/DAC systems.
