Product details
Overview
MAX6195AESA+T from Maxim Integrated is a precision, micropower, low-dropout series voltage reference delivering 5.000V output with ±2mV initial accuracy, 5ppm/°C max temperature coefficient, and 35µA max quiescent current - designed for high-accuracy ADC/DAC biasing in battery-powered instrumentation.
For engineers reviewing the MAX6195AESA+T datasheet, MAX6195AESA+T pinout, MAX6195AESA+T application, or MAX6195AESA+T equivalent, this page delivers verified specifications, SO-8 package details, load-regulation behavior at 500µA, dropout performance down to 100mV, and real-world alternatives for precision analog systems requiring long-term stability and low-noise references.
Technical Context
The MAX6195AESA+T employs a curvature-corrected bandgap core with laser-trimmed thin-film resistors to achieve <5ppm/°C temperature drift and ±2mV (±0.04%) initial tolerance. It operates as a series-mode reference, sourcing or sinking up to ±500µA while maintaining regulation.
Internally compensated for stability with capacitive loads up to 2.2nF, it achieves 220µs turn-on settling time to 0.1% and exhibits 0.17µV/µA load regulation and 25µV/V line regulation - enabling use in fast-settling, low-power precision data acquisition circuits without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.000V ±2mV (guaranteed over -40°C to +85°C; enables direct 5V system reference without trimming) |
| Temp Coefficient | ≤5ppm/°C (max; ensures <±0.25mV drift across full industrial temperature range) |
| Quiescent Current | ≤35µA (max; supports >10-year battery life in µA-level portable instruments) |
| Dropout Voltage | 100mV at 500µA load (allows operation from 5.1V supply in 5V systems with margin) |
| Load Regulation | 0.17µV/µA (enables stable reference under dynamic load changes up to ±500µA) |
| Noise (0.1–10Hz) | 240µVP-P (supports 18-bit+ ADC accuracy without additional filtering) |
| Capacitive Load Stability | 0–2.2nF (no minimum COUT required; saves board space in compact designs) |
Pinout & Package
MAX6195AESA+T is housed in an 8-pin SO (Small Outline) package, RoHS-compliant and rated for -40°C to +85°C operation. Pin 1 is OUT, Pin 2 is IN, Pin 4 is GND; Pins 1, 3, 5, 7, and 8 are No Connect (N.C.).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | 5.000V precision reference output; connects directly to ADC REF+, DAC VREF, or op-amp bias networks |
| 2 | IN | Input supply (VIN ≥ 5.1V); accepts 2.7V–12.6V with minimal supply-current variation |
| 4 | GND | Analog ground return; must be low-impedance path to avoid noise coupling into reference output |
| 3,5,7,8 | N.C. | No internal connection; may be left floating or tied to GND for mechanical stability (not electrically required) |
Key Features
| Feature | Design Value |
|---|---|
| Laser-trimmed thin-film resistors | Enables ±2mV initial accuracy and <5ppm/°C tempco without external calibration |
| Curvature-corrected bandgap core | Reduces parabolic error across temperature, delivering flat VOUT vs. T response |
| Series-mode architecture | Draws only 35µA quiescent current regardless of load - unlike shunt references that waste current at no load |
| Internal compensation | Stable with 0–2.2nF output capacitance; eliminates need for external compensation components |
| ±500µA sink/source capability | Drives ADC input buffers, op-amp references, and calibration DACs without external gain stages |

FAQ
What is the maximum load current supported by the MAX6195AESA+T?
The MAX6195AESA+T can source or sink up to ±500µA while maintaining output regulation within specification. At 500µA load, dropout is guaranteed ≤100mV, and load regulation is specified at 0.17µV/µA - ensuring stable 5.000V output even under full dynamic loading in precision analog circuits.
Does the MAX6195AESA+T require an output capacitor for stability?
No, the MAX6195AESA+T is internally compensated and stable with output capacitance ranging from 0 to 2.2nF. An external capacitor is optional and used only to improve transient response during load or supply steps - not required for basic stability, enabling minimalist PCB layouts in space-constrained designs.
What is the supply voltage range for reliable operation of the MAX6195AESA+T?
The MAX6195AESA+T operates reliably with input voltage from (VOUT + 0.2V) = 5.2V minimum up to 12.6V maximum. For 5.000V output, VIN ≥ 5.2V ensures regulation; typical applications use 5.5V or higher to accommodate dropout and line variation while staying within absolute maximum ratings.
How does the MAX6195AESA+T compare to shunt voltage references in battery-powered systems?
Unlike shunt references that draw constant current (including at zero load), the MAX6195AESA+T draws only 35µA quiescent current - independent of load. This eliminates wasted current during idle periods, significantly extending battery life in intermittent-use instruments such as handheld meters and portable sensors.
Is the MAX6195AESA+T pin-compatible with other devices in the MAX6190–MAX6198 family?
Yes, all members of the MAX6190–MAX6195/MAX6198 family share identical 8-pin SO packaging and pinout (IN, GND, OUT, N.C.), enabling drop-in replacement across output voltages (1.25V to 5.000V) and accuracy grades (A/B/C). The MAX6195AESA+T uses the same footprint as MAX6192AESA+T (2.5V) or MAX6198AESA+T (4.096V), simplifying multi-voltage design reuse.
