Product details
Overview
MAX6195CESA+T from Maxim Integrated is a precision, micropower, low-dropout series voltage reference delivering a stable 5.000V output with ±2mV initial accuracy, 5ppm/°C max temperature coefficient, and only 35µA max quiescent supply current. It operates from (VOUT + 0.2V) to 12.6V input, supports ±500µA load current, and is used in high-accuracy ADC/DAC biasing, portable instrumentation, and industrial process control systems requiring long-term stability and low power.
For engineers reviewing the MAX6195CESA+T datasheet, MAX6195CESA+T pinout, MAX6195CESA+T application, or MAX6195CESA+T equivalent, this page provides verified technical context, real-world design meaning for key specs, SO-8 package terminal mapping, application-specific implementation value, and two confirmed alternative parts with documented functional and parametric differences.
Technical Context
This device is a series-mode bandgap voltage reference employing proprietary curvature-correction circuitry and laser-trimmed thin-film resistors to achieve <5ppm/°C temperature coefficient and ±2mV initial accuracy. It sources and sinks up to 500µA while maintaining ≤100mV dropout at full load and exhibits 0.17µV/µA load regulation and 25µV/V line regulation.
Internally compensated for stability with capacitive loads up to 2.2nF, it achieves 220µs turn-on settling time to 0.1% and delivers 240µVRMS (10Hz–10kHz) noise performance. Its supply current remains virtually invariant across input voltage (0.8µA/V variation), enabling predictable battery-life estimation in portable systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.000V ±2mV (guaranteed initial tolerance enables direct replacement of 5V references without system recalibration) |
| Temp Coefficient | ≤5ppm/°C (max drift of ±0.25mV over -40°C to +85°C ensures stable ADC reference across industrial temperature range) |
| Quiescent Current | ≤35µA (enables >1-year operation on a single CR2032 coin cell in always-on sensor nodes) |
| Dropout Voltage | ≤100mV at 500µA load (supports operation from 5.1V rail when main supply sags, preserving reference integrity) |
| Load Regulation | 0.17µV/µA (output shifts <85µV across full ±500µA load range-critical for ratiometric DAC feedback loops) |
| Line Regulation | 25µV/V (output varies <250µV over 10V input swing-minimizes sensitivity to unregulated supply ripple) |
| Noise (10Hz–10kHz) | 240µVRMS (low enough to support 16-bit ADCs without external filtering in precision data acquisition) |
Pinout & Package
MAX6195CESA+T is housed in an 8-pin SO (Small Outline) package, RoHS-compliant, with exposed pad not electrically connected. Pin 1 is marked by a beveled corner or dot; pins are numbered counterclockwise.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 7, 8 | N.C. | No internal connection-no routing or thermal relief required; may be left floating or tied to GND for mechanical stability |
| 2 | IN | Positive supply input; must exceed VOUT + 0.2V; accepts up to 12.6V; decoupling capacitor recommended near pin |
| 4 | GND | Analog ground reference; requires low-impedance connection to system AGND plane to minimize noise coupling |
| 6 | OUT | Precision 5.000V reference output; capable of sourcing/sinking ±500µA; stable with 0–2.2nF capacitive load |
Key Features
| Feature | Design Value |
|---|---|
| Initial Accuracy | ±2mV (0.04% of 5V)-eliminates need for post-assembly trimming in production test flow |
| Temperature Drift | ≤5ppm/°C-ensures <±0.43mV total drift over -40°C to +85°C, meeting Class A industrial sensor requirements |
| Supply Current Stability | 0.8µA/V input variation-enables accurate battery-life modeling across wide input voltage transients |
| Capacitive Load Tolerance | 0–2.2nF-allows use without output capacitor in space-constrained PCBs, reducing BOM count and layout area |
| Turn-On Settling | 220µs to 0.1%-fast enough for microcontroller wake-up sequences without delaying ADC conversions |
Applications
| Portable Data Loggers | Industrial 4–20mA Transmitters |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR4550BRZ | 5.0V output, ±1mV initial accuracy, 3ppm/°C TC, 950µA supply current, SO-8 package | Higher power consumption limits use in battery-operated devices; superior TC suits ultra-stable lab equipment | Select ADR4550BRZ when ultimate temperature stability outweighs battery life; avoid in energy-harvesting designs |
| REF5050AIDR | 5.0V output, ±0.5mV initial accuracy, 3ppm/°C TC, 1.1mA supply current, SO-8 package | Higher drive capability (10mA) but 31× higher quiescent current; requires larger input headroom (1.2V dropout) | Choose REF5050AIDR for high-current reference buffering; MAX6195CESA+T preferred for micropower or low-headroom systems |
Compared with ADR4550BRZ and REF5050AIDR, MAX6195CESA+T uniquely balances sub-2mV accuracy, 5ppm/°C drift, and 35µA supply current in SO-8-making it optimal for portable, battery-critical, and low-input-headroom precision systems where alternatives trade power for stability or drive strength.

FAQ
What is the maximum load current supported by MAX6195CESA+T?
MAX6195CESA+T supports sourcing and sinking up to ±500µA while maintaining specified accuracy and dropout voltage. At 500µA load, dropout is guaranteed ≤100mV. Exceeding this current may cause output voltage deviation beyond datasheet limits or thermal stress. For higher current needs, consider adding an external buffer amplifier driven by MAX6195CESA+T.
Does MAX6195CESA+T require an output capacitor for stability?
No, MAX6195CESA+T is internally compensated and stable with capacitive loads from 0 to 2.2nF. An output capacitor is optional and only recommended in applications subject to fast load or supply transients to improve transient response and reduce overshoot. Omitting it saves board space and BOM cost in static-load applications like precision ADC reference.
What is the minimum input voltage required for MAX6195CESA+T to regulate at 5.000V?
The minimum input voltage for MAX6195CESA+T is VOUT + 0.2V = 5.2V under all operating conditions, per the datasheet's guaranteed dropout specification. At 500µA load, dropout is ≤100mV, so 5.1V input may suffice-but 5.2V is the validated minimum to ensure compliance across temperature and process variation. Below this, regulation is not guaranteed.
How does the supply current of MAX6195CESA+T vary with temperature?
MAX6195CESA+T quiescent supply current remains tightly controlled: 27µA (min) to 35µA (max) across -40°C to +85°C. Typical current is ~30µA at +25°C and increases only marginally at extremes-less than 2µA difference between -40°C and +85°C. This stability simplifies power budgeting in wide-temperature deployments.
Is MAX6195CESA+T pin-compatible with other devices in the MAX6190 family?
Yes, all MAX6190–MAX6195/MAX6198 variants-including MAX6195CESA+T-share identical 8-pin SO package, pinout (IN, GND, OUT, N.C.), and footprint. Substituting another member (e.g., MAX6193CESA+T for 3.0V) requires only changing the part number; no PCB redesign is needed. However, verify input voltage range and load requirements match the new output voltage.
