ADR3550WARMZ-R7

Overview

The ADR3550WARMZ-R7 is a micropower, high-precision CMOS voltage reference with a nominal output of 5.000 V. It operates within an input voltage range of 5.2 V to 5.5 V and supports an output current capacity of +10 mA source and -3 mA sink. The device features a maximum temperature coefficient of 8 ppm/°C (A grade) and an initial output voltage error of ±0.1%. Quiescent current is 100 μA maximum in normal operation and 5 μA in shutdown. It includes an enable pin for power management and is qualified for automotive applications.

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 the device to be shut down or enabled based on logic levels relative to the input voltage.

Applications

Automotive battery monitors
Portable instrumentation
Process transmitters
Remote sensors
Medical instrumentation

Procurement Notes

Verify the specific grade (A or B) required for your application, as the datasheet specifies different temperature coefficients for each. Confirm that the input voltage supply remains strictly within the 5.2 V to 5.5 V range to ensure proper regulation. Ensure the PCB layout supports the 4-wire Kelvin connection scheme using the dedicated Force and Sense pins for optimal precision.

Selection Notes

Select this component when a 5.0 V reference is needed with strict limits on quiescent current and physical footprint. The MSOP-8 package is suitable for space-constrained designs. Consider the A grade if the maximum temperature coefficient must not exceed 8 ppm/°C across the full automotive temperature range. Verify that the load requirements do not exceed the sourcing/sinking current capabilities.

Part Context

This part belongs to the ADR35xx series of micropower voltage references from Analog Devices. The series includes variants with outputs of 2.5 V, 3.0 V, 3.3 V, and 4.096 V. All members share similar architectural benefits, including low noise, low dropout voltage, and automotive qualification, packaged in an 8-lead MSOP form factor.
