Product details
Overview
MAX6070BAUT33/V+ from Analog Devices is a precision 3.3V 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), 9.6µVP-P 0.1Hz–10Hz noise, 150µA supply current, and supports ±10mA load sourcing/sinking - enabling high-accuracy ADC/DAC biasing in industrial process control systems.
For engineers reviewing the MAX6070BAUT33/V+ datasheet, MAX6070BAUT33/V+ pinout, MAX6070BAUT33/V+ application, or MAX6070BAUT33/V+ equivalent, key selection criteria include its integrated noise-filter option (FILTER pin), force-sense output architecture for remote sensing, AEC-Q100 qualification, and guaranteed operation from –40°C to +125°C with <150mV dropout at 10mA.
Technical Context
The MAX6070BAUT33/V+ implements a bandgap-based series voltage reference with dual-output force-sense topology: OUTF provides regulated output drive while OUTS enables Kelvin sensing at the load to reject PCB trace resistance errors. Its FILTER pin accepts an external 0.1µF capacitor to suppress high-frequency noise beyond 10kHz.
This device operates as a low-dropout (LDO-style) reference requiring only 4.3V minimum input for 3.3V output, achieving 80dB ripple rejection at 60Hz and stable performance into capacitive loads from 0.1µF to 10µF. It features enable-controlled shutdown (6µA ISD) and exhibits 35ppm long-term stability over 1000 hours.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.300V ±0.04% at +25°C - ensures direct compatibility with 3.3V logic and SAR ADC reference inputs without trimming. |
| Temp Drift (max) | 6ppm/°C (A grade) - limits full-scale error to ≤±792ppm (±0.0792%) across –40°C to +125°C span. |
| 1/f Noise | 9.6µVP-P (0.1Hz–10Hz) - preserves resolution in 24-bit delta-sigma ADCs used in precision weigh scales. |
| Supply Current | 150µA typical - enables battery-powered portable instrumentation with multi-year runtime. |
| Load Drive | ±10mA sourcing/sinking - supports driving 10kΩ DAC reference inputs or multiple parallel ADCs. |
| Dropout Voltage | 75mV min (150mV max) at 10mA - allows operation from 3.3V+0.15V = 3.45V supply, easing LDO selection. |
| Ripple Rejection | 80dB at 60Hz - rejects power-supply hum in PLC analog input modules powered from unregulated rails. |
Pinout & Package
Package: 6-pin SOT23 (package code U6+5A), 2.9mm × 1.6mm footprint, JEDEC MS-012 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| FILTER (Pin 1) | Noise filter input | Accepts 0.1µF capacitor to GND; enables wideband noise suppression without affecting DC accuracy. |
| GNDF (Pin 2) | Force ground | Provides dedicated return path for OUTF; separates high-current return from sensitive sense node. |
| EN (Pin 3) | Enable control | Logic-compatible input (VIH = 0.7×VIN); asserts internal bandgap core when high, reduces IIN to 6µA when low. |
| IN (Pin 4) | Supply input | Accepts 4.3V to 5.5V; internal regulation maintains VOUT despite input ripple or sag. |
| OUTS (Pin 5) | Sense output | Connects directly to load ground; enables remote sensing to cancel IR drop in PCB traces. |
| OUTF (Pin 6) | Force output | Delivers regulated 3.3V; bypassed locally with 0.1–10µF capacitor to stabilize loop response. |
Key Features
| Feature | Design Value |
|---|---|
| Force-sense output architecture | Eliminates voltage error from PCB trace resistance up to 100mΩ, critical for ±0.01% system accuracy. |
| Integrated noise filter option | FILTER pin enables configurable high-frequency noise attenuation without external op-amp circuitry. |
| AEC-Q100 qualified | Validated for automotive applications including engine control units and ADAS sensor signal conditioning. |
| Low 150µA quiescent current | Reduces self-heating to <0.5°C rise, minimizing thermal drift contribution in sealed enclosures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF5033IDR | Higher 3ppm/°C max drift, 3.8µVP-P noise, but no FILTER pin or force-sense outputs; SOIC-8 package. | Lacks remote sensing capability; requires external Kelvin routing for equivalent accuracy; larger footprint. | Select when ultra-low noise dominates over layout flexibility and board space is not constrained. |
| ADR4533BRZ | Lower 3ppm/°C max drift, 4.5µVP-P noise, integrated hysteresis-free enable, but no FILTER pin; SOIC-8 package. | No force-sense architecture; relies on single-output topology with higher sensitivity to PCB IR drop. | Choose for highest DC precision where remote sensing is unnecessary and SOIC-8 is acceptable. |
Compared with REF5033IDR and ADR4533BRZ, the MAX6070BAUT33/V+ trades marginally higher noise for unique force-sense capability and SOT23 size-enabling accurate ratiometric measurements in space-constrained industrial sensors without layout compromises.

FAQ
What is the maximum input voltage rating for MAX6070BAUT33/V+?
The absolute maximum input voltage for MAX6070BAUT33/V+ is +6V, as specified in the Absolute Maximum Ratings table. However, the recommended operating range is 4.3V to 5.5V for reliable 3.3V output regulation with minimal dropout and optimal noise performance. Exceeding 5.5V may increase power dissipation and thermal drift without functional benefit.
Does MAX6070BAUT33/V+ require an external capacitor on the FILTER pin?
No - the FILTER pin on MAX6070BAUT33/V+ is optional. It must be left open-circuit if high-frequency noise filtering is not required. When used, a 0.1µF ceramic capacitor to ground is recommended to reduce thermal noise above 10kHz while preserving DC accuracy and settling time.
Can MAX6070BAUT33/V+ drive a 10µF output capacitor?
Yes - MAX6070BAUT33/V+ is specified for stable operation with output capacitance from 0.1µF to 10µF, including ceramic, tantalum, and polymer types. This range accommodates bulk decoupling for multi-channel data acquisition systems without risk of oscillation or degraded transient response.
How does the force-sense architecture of MAX6070BAUT33/V+ improve system accuracy?
The force-sense architecture of MAX6070BAUT33/V+ separates OUTF (power delivery) and OUTS (voltage sensing) paths, allowing OUTS to connect directly at the load. This eliminates voltage drop errors caused by PCB trace resistance between the IC and ADC reference input - improving end-to-end accuracy by up to 100µV in typical 50mΩ trace scenarios.
Is MAX6070BAUT33/V+ qualified for automotive applications?
Yes - MAX6070BAUT33/V+ is AEC-Q100 qualified (Grade 1: –40°C to +125°C), with full test documentation covering HTOL, TC, ESD, and AC/DC parametric validation. It is approved for use in non-safety-critical automotive subsystems including cabin temperature sensors, battery monitoring, and infotainment power management.
