Product details
Overview
MAX6133BASA50+T from Maxim Integrated is a precision series-mode voltage reference IC delivering 5.000V output with ±0.08% initial accuracy, 5ppm/°C max temperature coefficient (−40°C to +125°C), and 200mV max dropout voltage. It operates from 5.2V to 12.6V input, supplies up to 15mA load current, and draws only 40µA quiescent supply current-ideal for high-accuracy A/D converters and portable instrumentation.
For engineers reviewing the MAX6133BASA50+T datasheet, MAX6133BASA50+T pinout, MAX6133BASA50+T application, or MAX6133BASA50+T equivalent, key selection criteria include guaranteed initial accuracy over temperature, low-noise performance (40µVP-P, 0.1Hz–10Hz), wide input range, and SO-8 package compatibility with space-constrained industrial and battery-powered systems.
Technical Context
The MAX6133BASA50+T is a bandgap-based series voltage reference using laser-trimmed thin-film resistors and post-package trimming to achieve tight initial accuracy and stability. Its architecture enables low-noise operation and excellent line regulation (≤30µV/V) without external components beyond minimal bypass capacitors.
It functions as a three-terminal active regulator: IN supplies power, GND establishes reference ground, and OUT delivers a stable 5.000V reference. The device maintains regulation down to 200mV headroom and supports sourcing up to 15mA while consuming <85µA across −40°C to +125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.000V ±0.08% at +25°C - ensures 14-bit DAC accuracy over full temperature range |
| Tempco | 5ppm/°C max (−40°C to +125°C) - limits drift to ≤0.625mV over full range |
| Dropout Voltage | 200mV max at 10mA - enables operation from 5.2V supply with margin |
| Quiescent Current | 40µA typical - extends battery life in portable instruments |
| Load Regulation | 0.01–0.10mV/mA - maintains stability under dynamic load changes |
| Noise (0.1–10Hz) | 40µVP-P - minimizes quantization error in precision ADCs |
| Line Regulation | 2–50µV/V - rejects supply ripple without additional filtering |
Pinout & Package
MAX6133BASA50+T is housed in an 8-pin SO (SOIC-N) package measuring 5.00mm × 4.00mm × 1.50mm, with standard 1.27mm pitch and gull-wing leads. RoHS-compliant and rated for −40°C to +125°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 7 | No Connection (N.C.) | Internally unconnected; must remain floating or tied to GND per layout best practice |
| 2 | IN | Positive supply input; requires ≥5.2V, supports up to 12.6V with 0.1µF ceramic decoupling |
| 4 | GND | Analog ground reference; common return for IN and OUT paths |
| 5, 8 | I.C. | Internally connected; no external connection permitted |
| 6 | OUT | Stable 5.000V reference output; requires ≥0.1µF ceramic capacitor to GND for stability |
Key Features
| Feature | Design Value |
|---|---|
| Laser-trimmed thin-film resistors | Enables ±0.08% initial accuracy without external calibration |
| Post-package trimming | Compensates for package-induced stress, improving long-term stability to 40ppm (1000h) |
| Bandgap core with low-noise design | Delivers 40µVP-P (0.1–10Hz) noise-critical for 16-bit+ data acquisition |
| Series-mode topology | Eliminates shunt resistor losses; reduces system power vs. 2-terminal references |
| Wide input voltage range | 2.7V to 12.6V (voltage-dependent) - supports single-supply operation across multiple rails |

FAQ
What is the maximum load current supported by the MAX6133BASA50+T?
The MAX6133BASA50+T supports up to 15mA of output source current while maintaining regulation and specified accuracy. Load regulation is guaranteed at 0.01–0.10mV/mA across the full −100µA to +15mA range, making it suitable for driving ADC reference inputs, op-amp bias networks, and small logic loads without external buffering.
Does the MAX6133BASA50+T require external capacitors for stability?
Yes-the MAX6133BASA50+T requires a minimum 0.1µF ceramic capacitor from OUT to GND for stability and is stable with output capacitance up to 100µF. An optional 0.1µF ceramic capacitor from IN to GND improves line-transient response. Both capacitors must be placed as close as possible to their respective pins to minimize parasitic inductance.
What is the input voltage range for reliable operation of the MAX6133BASA50+T?
The MAX6133BASA50+T operates reliably with input voltages from 5.2V to 12.6V when configured for 5.000V output. This range is derived from the dropout specification (200mV max) and line regulation test conditions. Operation below 5.2V risks loss of regulation; above 12.6V exceeds absolute maximum ratings and may cause permanent damage.
How does the MAX6133BASA50+T compare to the A-grade version (MAX6133AASA50+T)?
The MAX6133BASA50+T has ±0.08% initial accuracy and 5ppm/°C max tempco, whereas the A-grade MAX6133AASA50+T offers ±0.04% initial accuracy and 3ppm/°C max tempco. Both share identical SO-8 packaging, 40µA quiescent current, and 200mV dropout. The B-grade trades tighter specs for cost efficiency in applications where 0.08% accuracy suffices.
Can the MAX6133BASA50+T be used to generate a negative reference voltage?
Yes-the MAX6133BASA50+T can be used with an external rail-to-rail op-amp (e.g., MAX400) to create a precision negative reference, as shown in Figure 2 of the datasheet. The circuit inverts the 5.000V output to −5.000V with low offset and noise, eliminating discrete resistors and saving board space in cost- and size-sensitive applications.
