Analog Devices Inc./Maxim Integrated MAX6062BEUR+T

Overview

MAX6062BEUR+T from Maxim Integrated is a precision, low-dropout, micropower 2.048V voltage reference in a 3-pin SOT23 package. It delivers ±0.39% initial accuracy, 20ppm/°C max temperature coefficient, and supports 5mA sourcing / 2mA sinking across –40°C to +85°C. It enables high-accuracy ADC biasing in portable instrumentation where board space and battery life are critical.

For engineers reviewing the MAX6062BEUR+T datasheet, MAX6062BEUR+T pinout, MAX6062BEUR+T application, or MAX6062BEUR+T equivalent, key selection criteria include dropout voltage (200mV max at 1mA), supply-current independence from VIN (90µA typical, 8µA/V variation), absence of required output capacitor, and stable operation with capacitive loads - all essential for low-power, space-constrained analog signal chains.

Technical Context

The MAX6062BEUR+T is a three-terminal series-mode voltage reference featuring proprietary curvature-correction circuitry and laser-trimmed thin-film resistors. Its architecture eliminates external compensation components while maintaining stability with capacitive loads up to 1µF.

It operates over an input range of 2.5V to 12.6V, with dropout voltage defined as the minimum VIN–VOUT differential sustaining ≤0.2% output error. Load regulation is specified separately for sourcing (0–5mA) and sinking (–2mA–0) conditions, reflecting true bidirectional current capability.

FAQ

What is the maximum load current the MAX6062BEUR+T can source or sink?

The MAX6062BEUR+T can source up to 5mA and sink up to 2mA while maintaining output accuracy within specifications. This bidirectional capability allows it to directly drive ADC reference inputs, op-amp bias networks, and DAC references without external buffers - a key advantage over shunt references that only sink current. The MAX6062BEUR+T's load regulation is characterized separately for sourcing and sinking conditions to reflect real-world behavior.

Does the MAX6062BEUR+T require an output capacitor for stability?

No, the MAX6062BEUR+T is internally compensated and does not require an external output capacitor for stability - even with capacitive loads up to 1µF. This eliminates a common BOM item and saves PCB area in space-critical designs like handheld instruments and wearables. While optional output capacitance improves transient response during load steps, its omission has no impact on DC accuracy or AC stability of the MAX6062BEUR+T.

What is the input voltage range for reliable operation of the MAX6062BEUR+T?

The MAX6062BEUR+T operates reliably from 2.5V to 12.6V input voltage. Its minimum input is defined by the 200mV max dropout specification - meaning 2.5V is sufficient to deliver 2.048V output at 1mA load. At higher loads or elevated temperatures, VIN should exceed VOUT by ≥250mV to ensure full specification compliance. Input voltage beyond 12.6V risks damage per absolute maximum ratings.

How does the MAX6062BEUR+T compare to shunt voltage references in terms of supply current efficiency?

Unlike shunt references that draw constant current through an external resistor (wasting power regardless of load), the MAX6062BEUR+T draws only 90µA quiescent current - virtually independent of input voltage (≤8µA/V variation). It supplies load current on-demand, eliminating wasted bias current. This architecture maximizes battery life in portable systems and reduces thermal load in sealed enclosures - a fundamental efficiency advantage inherent to the MAX6062BEUR+T's series-mode topology.

Is the MAX6062BEUR+T suitable for use with high-resolution ADCs such as 16-bit or 18-bit converters?

Yes, the MAX6062BEUR+T supports high-resolution ADCs: its 22µV_P-P (0.1–10Hz) noise contributes <0.01 LSB error to a 16-bit 2.048V-range ADC, and its 20ppm/°C tempco introduces <±0.03% gain error over –40°C to +85°C - well within typical 16-bit system tolerances. For 18-bit systems, verify total system noise budget and consider layout isolation, but the MAX6062BEUR+T remains a validated, production-ready reference choice per Maxim's application data.
