Product details
Overview
MAX6070BAUT41+ from Analog Devices is a precision 4.096V low-noise, low-drift series voltage reference in a 6-pin SOT23 package. It delivers ±0.04% initial accuracy, 6ppm/°C max temperature drift (A grade), and 9µVP-P 0.1Hz–10Hz noise - enabling high-accuracy ADC/DAC biasing in industrial process control systems.
For engineers reviewing the MAX6070BAUT41+ datasheet, MAX6070BAUT41+ pinout, MAX6070BAUT41+ application, or MAX6070BAUT41+ equivalent, key selection criteria include its 4.096V output matched to 12-bit/16-bit SAR ADC full-scale ranges, filter-enabled wideband noise suppression, and AEC-Q100 qualification for automotive sensor signal conditioning.
Technical Context
The MAX6070BAUT41+ implements a bandgap-based series reference architecture with dual-output force-sense topology (OUTF/GNDF and OUTS/GNDS) to reject PCB trace resistance errors. Its integrated FILTER pin accepts an external 0.1µF capacitor to suppress >10kHz noise without compromising DC stability.
It operates from 5.2V to 5.5V input, sustains ±10mA load current with ≤150mV dropout at 10mA, and achieves 74dB ripple rejection at 60Hz - making it suitable for noisy power-rail environments where reference integrity directly impacts measurement linearity.
Key Specifications

FAQ
What output voltage does the MAX6070BAUT41+ provide?
The MAX6070BAUT41+ provides a precise 4.096V output voltage. This value is selected to match the full-scale range of 12-bit analog-to-digital converters (2¹² = 4096), eliminating scaling errors in data acquisition systems. The device maintains this voltage with ±0.04% initial accuracy at +25°C and 6ppm/°C maximum temperature drift across –40°C to +125°C.
Does the MAX6070BAUT41+ support remote sensing?
Yes, the MAX6070BAUT41+ supports true remote Kelvin sensing via separate OUTS (sense) and OUTF (force) outputs. The OUTS pin connects directly to the load's ground reference point, while OUTF delivers the regulated 4.096V. Shorting these pins at the load minimizes errors caused by PCB trace resistance - critical for maintaining accuracy in high-current or long-trace applications.
How does the FILTER pin on the MAX6070BAUT41+ function?
The FILTER pin on the MAX6070BAUT41+ accepts an external 0.1µF capacitor to ground, forming a low-pass filter that attenuates high-frequency noise (>10kHz) without affecting DC regulation or transient response. When used, it reduces thermal noise by up to 20dB while preserving 0.01% settling in 10ms - ideal for wideband applications like audio ADCs or RF receiver biasing.
Is the MAX6070BAUT41+ qualified for automotive use?
Yes, the MAX6070BAUT41+ is AEC-Q100 qualified for automotive applications. It is specified over the extended temperature range of –40°C to +125°C and designed for reliability in safety-critical subsystems such as engine control units, brake-by-wire interfaces, and ADAS sensor signal chains where stable voltage references directly impact functional safety compliance.
What is the minimum input voltage required for the MAX6070BAUT41+ to regulate at 4.096V?
The MAX6070BAUT41+ requires a minimum input voltage of 5.2V to maintain regulation at 4.096V across its full operating range. Its dropout voltage is specified as 60–150mV at 10mA load current, meaning VIN must exceed VOUT by at least this margin. At light loads, regulation is maintained down to 5.2V; at full 10mA sink/source, VIN ≥ 5.25V is recommended per datasheet characterization.
