Product details
Overview
MAX6192BESA from Maxim Integrated is a precision, micropower, low-dropout series-mode bandgap voltage reference delivering 2.500V output with ±2mV initial accuracy, 5ppm/°C max temperature coefficient, and 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 where stable low-power references are critical.
For engineers reviewing the MAX6192BESA datasheet, MAX6192BESA pinout, MAX6192BESA application, or MAX6192BESA equivalent, key selection criteria include guaranteed 2.500V output tolerance, dropout voltage ≤100mV at 500µA, load regulation of 0.14µV/µA, line regulation of 15µV/V, and stability with up to 2.2nF capacitive loads without external compensation.
Technical Context
The MAX6192BESA employs a proprietary curvature-correction circuit and laser-trimmed thin-film resistors to achieve <5ppm/°C temperature coefficient and ±2mV initial accuracy over -40°C to +85°C. Its series-mode architecture enables bidirectional load current (±500µA) and eliminates need for external biasing resistors.
Internally compensated design ensures fast settling (85µs to 0.1%) and unconditional stability with capacitive loads from 0 to 2.2nF. Supply current remains virtually invariant across input voltage (0.8µA/V variation), making it suitable for battery-powered systems with variable supply rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.500V ±2mV - tight initial tolerance enables direct use in 12-bit+ ADC/DAC reference paths without trimming. |
| Temp Coefficient | ≤5ppm/°C - ensures <±125µV drift over full -40°C to +85°C range, critical for precision measurement systems. |
| Quiescent Current | ≤35µA - ultra-low power draw extends battery life in handheld instruments and remote sensors. |
| Dropout Voltage | ≤100mV at 500µA - allows operation from 2.6V input in 2.5V systems, supporting low-voltage microcontroller designs. |
| Load Regulation | 0.14µV/µA - minimal output shift under varying load ensures stable reference for ratiometric sensor interfaces. |
| Line Regulation | 15µV/V - suppresses supply ripple effects, maintaining accuracy even with noisy or unregulated inputs. |
| Noise (0.1–10Hz) | 125µVRMS - low flicker noise preserves signal integrity in high-resolution data acquisition. |
Pinout & Package
MAX6192BESA is housed in an 8-pin SO (Small Outline) package with RoHS-compliant lead-free finish. Pin 1, 3, 5, 7, and 8 are No Connect (N.C.), Pin 4 is GND, Pin 6 is OUT (2.500V reference output), and Pin 2 is IN (supply input).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 7, 8 | No Connection | Not internally connected; must remain floating or tied to GND per layout best practices. |
| 2 | IN | Supply input terminal; accepts 2.7V to 12.6V; requires local decoupling for noise rejection. |
| 4 | GND | Analog ground reference; must be low-impedance connection to system ground plane. |
| 6 | OUT | Precision 2.500V reference output; capable of sourcing/sinking ±500µA with minimal regulation error. |
Key Features
| Feature | Design Value |
|---|---|
| Laser-trimmed thin-film resistors | Enable ±2mV initial accuracy and <5ppm/°C tempco without external calibration. |
| Curvature-correction circuit | Compensates second-order thermal effects, achieving flat VOUT vs. temperature response. |
| Internal compensation | Eliminates need for external compensation components; stable with 0–2.2nF capacitive loads. |
| Bidirectional load capability | Sinks or sources up to 500µA, enabling use in both active and passive reference configurations. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF3025AIDBZR | 2.5V output, ±0.2% initial accuracy (±5mV), 50ppm/°C max tempco, 50µA supply current. | Higher initial error and tempco; suited for cost-sensitive, lower-accuracy applications. | Select REF3025AIDBZR only when ±5mV tolerance and relaxed drift specs are acceptable. |
| ADR3425ARJZ-R7 | 2.5V output, ±0.12% initial accuracy (±3mV), 10ppm/°C max tempco, 120µA supply current. | Higher quiescent current limits battery life; better initial accuracy but worse tempco than MAX6192BESA. | Choose ADR3425ARJZ-R7 if tighter initial spec is prioritized over low power and long-term stability. |

FAQ
What is the output voltage tolerance of MAX6192BESA over temperature?
MAX6192BESA guarantees 2.500V ±2mV initial accuracy at +25°C and maintains output stability within ±125µV (±50ppm) over the full -40°C to +85°C operating range due to its ≤5ppm/°C temperature coefficient. This performance is achieved via proprietary curvature correction and laser trimming, and is validated across production lots-not estimated or typical-only.
Can MAX6192BESA drive a 2.2nF capacitive load without oscillation?
Yes, MAX6192BESA is internally compensated and specified to remain stable with capacitive loads from 0 to 2.2nF. This eliminates the need for external compensation networks and simplifies layout in noise-sensitive applications such as precision data acquisition. Stability is guaranteed across temperature and load conditions per the datasheet's capacitive-load stability range specification.
What is the minimum input voltage required for MAX6192BESA to maintain regulation?
The minimum input voltage for MAX6192BESA is VOUT + 0.2V = 2.7V. At 500µA load, dropout voltage is guaranteed ≤100mV, meaning regulation is maintained down to 2.6V input-enabling reliable operation in 2.7V and higher single-cell lithium or regulated 3.3V systems without headroom margin compromise.
Does MAX6192BESA support sinking current, and how much?
Yes, MAX6192BESA supports bidirectional load current: it can source or sink up to ±500µA while maintaining specified load regulation (0.14µV/µA). This capability allows use in active filter biasing, current-source references, and circuits requiring pull-down functionality-unlike many shunt references that only sink or require external components for bidirectional operation.
How does the supply current of MAX6192BESA vary with input voltage?
MAX6192BESA exhibits exceptionally stable quiescent supply current: maximum 35µA with only ±2µA variation across its full input range (2.7V to 12.6V), corresponding to a worst-case change of 0.8µA/V. This near-invariance simplifies power budgeting and eliminates supply-dependent drift in battery-powered systems where VIN declines during discharge.
