Product details
Overview
MAX6133BASA30+T from Maxim Integrated is a precision series voltage reference delivering 3.000V output with ±0.08% initial accuracy, 5ppm/°C max temperature coefficient (−40°C to +125°C), and 200mV max dropout voltage. It operates from 3.2V to 12.6V supply, draws only 40µA quiescent current, and supports up to 15mA source current - ideal for high-resolution ADC/DAC biasing in portable instrumentation.
For engineers reviewing the MAX6133BASA30+T datasheet, MAX6133BASA30+T pinout, MAX6133BASA30+T application, or MAX6133BASA30+T equivalent, this page delivers verified specifications, SO-8 package layout, real-world load/line regulation performance (0.06 mV/mA, 30 µV/V), thermal hysteresis (120 ppm), and validated alternatives for precision analog signal chains.
Technical Context
The MAX6133BASA30+T uses bandgap-based series-mode architecture with laser-trimmed thin-film resistors and post-package trimming to achieve tight initial accuracy and low drift. Its internal circuitry enables stable operation with 0.1µF–100µF output capacitance and eliminates external compensation components.
This device functions as a three-terminal active reference: IN supplies power, GND establishes reference ground, and OUT delivers regulated 3.000V. It features built-in short-circuit protection (±2mA), turn-on settling in 600µs to ±0.01%, and maintains regulation across −40°C to +125°C without derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.000V ±0.024V at +25°C - defines absolute scaling for 14-bit DACs requiring ≤0.5 LSB error over temperature |
| Initial Accuracy | ±0.08% max - guarantees output stays within ±2.4mV of 3.000V before calibration |
| Tempco | 5ppm/°C max (−40°C to +125°C) - contributes ≤1.5mV drift over full range, enabling <12-bit stability without trimming |
| Dropout Voltage | 200mV max at 10mA - allows operation from 3.2V supply while maintaining regulation, critical for single-cell Li-ion systems |
| Quiescent Current | 40µA typical - enables >1-year battery life in 10µA-sleep microcontroller systems with periodic ADC sampling |
| Load Regulation | 0.06 mV/mA max - ensures ≤0.9mV shift from 0 to 15mA load, preserving linearity in sensor front-ends |
| Noise (0.1–10Hz) | 24µVP-P - limits RMS noise contribution to <0.0008% of full-scale, suitable for 16-bit SAR ADC references |
Pinout & Package
MAX6133BASA30+T is housed in an 8-pin SO (SOIC-N) package measuring 4.90mm × 3.90mm × 1.75mm (max height), with standard 1.27mm lead pitch and RoHS-compliant matte tin plating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 7 | N.C. | No internal connection - must remain unconnected or tied to GND per layout best practice; no routing required |
| 2 | IN | Positive supply input - accepts 3.2V–12.6V; requires 0.1µF ceramic bypass capacitor placed adjacent to pin |
| 4 | GND | Analog ground reference - connects to system AGND plane; serves as return path for load current and internal bias |
| 5, 8 | I.C. | Internally connected - not user-accessible; must not be wired externally to avoid damage or instability |
| 6 | OUT | Stable 3.000V reference output - drives ADC REF+, DAC VREF, or op-amp gain-setting networks; requires ≥0.1µF output capacitor |
Key Features
| Feature | Design Value |
|---|---|
| Low dropout voltage | 200mV max enables use with 3.3V rails while retaining 3.000V output - avoids need for boost converters in space-constrained designs |
| Ultra-low quiescent current | 40µA independent of input voltage - reduces standby power by >90% vs. shunt references, extending battery runtime |
| Laser-trimmed accuracy | ±0.08% initial tolerance achieved via post-package trimming - eliminates field calibration for industrial sensor nodes |
| Wide supply range | 3.2V to 12.6V operation - supports direct connection to unregulated wall adapters or multi-cell battery stacks |
| Thermal hysteresis control | 120ppm typical - ensures repeatable output after thermal cycling, critical for metrology-grade calibration equipment |

FAQ
What is the maximum load current supported by the MAX6133BASA30+T?
The MAX6133BASA30+T supports up to 15mA of output source current while maintaining regulation and specified accuracy. This capability allows direct driving of multiple ADC reference inputs, op-amp bias networks, or small-signal DACs without external buffering. Exceeding 15mA may cause dropout or increased output error beyond datasheet limits.
Does the MAX6133BASA30+T require external capacitors for stability?
Yes, the MAX6133BASA30+T requires a minimum 0.1µF ceramic capacitor between OUT and GND for stability, and recommends a 0.1µF capacitor between IN and GND for optimal line-transient response. The device remains stable with output capacitance up to 100µF, enabling improved transient immunity in noisy environments.
What is the operating temperature range for the MAX6133BASA30+T?
The MAX6133BASA30+T is rated for continuous operation from −40°C to +125°C. All key specifications - including initial accuracy, temperature coefficient, dropout voltage, and load regulation - are guaranteed across this full industrial temperature range, making it suitable for under-hood automotive and outdoor industrial deployments.
How does the MAX6133BASA30+T compare to shunt voltage references in terms of power efficiency?
The MAX6133BASA30+T consumes only 40µA quiescent current regardless of load, whereas shunt references draw constant current through a resistor divider. In a typical 3.3V system powering a 10mA load, the MAX6133BASA30+T saves ~30mW versus a 2.5V shunt reference with 10mA minimum cathode current - significantly extending battery life in portable devices.
Can the MAX6133BASA30+T be used to generate a negative reference voltage?
Yes, the MAX6133BASA30+T can serve as the positive reference for an op-amp configured as an inverting amplifier to produce a precise negative reference, as demonstrated in Maxim Application Note Figure 2 using the MAX400 op-amp. This topology avoids resistive dividers and maintains low noise and temperature drift in the inverted output.
