Product details
Overview
MAX6250BCSA+T from Maxim Integrated is a precision 5.000V buried-zener voltage reference IC with 5.0ppm/°C max temperature coefficient, ±0.02% initial accuracy, and 3.0µVP-P (0.1Hz–10Hz) output noise-designed for high-resolution ADC/DAC biasing in test equipment and industrial control systems.
For engineers reviewing the MAX6250BCSA+T datasheet, MAX6250BCSA+T pinout, MAX6250BCSA+T application, or MAX6250BCSA+T equivalent, key selection criteria include low-drift stability over temperature, ±15mA sourcing/sinking capability, optional external trim and noise reduction, and compatibility with capacitive loads up to 100µF without oscillation.
Technical Context
The MAX6250BCSA+T employs buried-zener core technology with on-chip temperature compensation to achieve near-zero curvature across –40°C to +85°C. Its output remains stable under load transients (settling to ±0.01% in 10µs) and exhibits <5ppm/mA load regulation when sourcing or sinking up to ±15mA.
It operates from 8V to 36V input, delivers 5.000V ±0.005V at +25°C, and maintains 20ppm/1000h long-term stability. The NR pin supports optional 1µF capacitor for wideband noise reduction, while TRIM enables ±30mV (±0.6%) adjustment without degrading temperature performance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.000V ±0.005V at +25°C - ensures accurate full-scale calibration for 16-bit data converters |
| Temp Coefficient | 5.0ppm/°C max (–40°C to +85°C) - guarantees ≤±0.5mV drift over industrial temperature range |
| Initial Accuracy | ±0.02% - enables single-point calibration in high-accuracy metering and ATE |
| Output Noise | 3.0µVP-P (0.1Hz–10Hz), 2.5µVRMS (10Hz–1kHz) - preserves SNR in precision analog front-ends |
| Load Current | ±15mA sourcing/sinking - supports direct drive of op-amp inputs and DAC references without buffering |
| Line Regulation | 7ppm/V (10V–36V) - minimizes output variation across unregulated supply rails |
| Long-Term Stability | 20ppm/1000h - reduces recalibration frequency in deployed instrumentation |
Pinout & Package
MAX6250BCSA+T is housed in an 8-pin SO (Small Outline) package with industry-standard footprint (S8+5, outline 21-0041), RoHS-compliant and lead-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8 | I.C. (Internally Connected) | No connection required; must be left unconnected per datasheet |
| 2 | IN | Positive power input (8V–36V); requires local bypass capacitor for ripple rejection |
| 3 | NR | Noise reduction node; accepts 1µF capacitor to reduce wideband output noise |
| 4 | GND | Analog ground reference; must be low-impedance and star-connected to minimize noise coupling |
| 5 | TRIM | External voltage-adjustment input; enables ±30mV trim via 10kΩ potentiometer without affecting tempco |
| 6 | OUT | Stable 5.000V reference output; capable of driving 100µF capacitive loads without instability |
Key Features
| Feature | Design Value |
|---|---|
| Buried-zener core | Enables ultra-low 3.0µVP-P (0.1Hz–10Hz) noise and 5.0ppm/°C tempco - critical for metrology-grade references |
| Optional NR capacitor | 1µF on NR pin reduces broadband noise by >10dB without compromising transient response or stability |
| ±15mA output drive | Eliminates need for external buffer op-amps in 16-bit SAR ADC reference paths and precision current sources |
| Trim-adjustable output | ±30mV (±0.6%) fine-tuning via TRIM pin preserves factory-calibrated tempco and long-term stability |
| Capacitive-load tolerant | Stable with 0–100µF output capacitance - simplifies layout and supports low-ESR ceramic or tantalum bypassing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF5050IDR | 5.0V output, 3ppm/°C max tempco, 1.6µVP-P noise, but only ±10mA output drive | Lower noise and tighter tempco, but insufficient drive for direct 15mA DAC reference loads | Select REF5050IDR only if load current ≤10mA and sub-2µV noise is mandatory |
| ADR4550BRZ | 5.0V output, 3ppm/°C max tempco, 1.75µVP-P noise, ±10mA drive, higher 4.8mA supply current | Superior noise/tempco specs, but requires external buffer for >10mA loads and consumes more power | Choose ADR4550BRZ when ultra-low drift dominates over drive capability and power budget |
Compared with REF5050IDR and ADR4550BRZ, MAX6250BCSA+T provides the highest output current drive (±15mA) among these 5V references, enabling direct interface with demanding loads like high-speed DACs and current sources without added components-making it optimal for space-constrained, high-fidelity analog signal chains.

FAQ
What is the maximum operating temperature range for MAX6250BCSA+T?
The MAX6250BCSA+T is rated for operation from –40°C to +85°C (industrial temperature range). This is confirmed by its "E" grade designation in the ordering table and validated across all electrical characteristics in the datasheet's E-grade columns. The device maintains full specification compliance-including 5.0ppm/°C tempco and ±0.02% initial accuracy-throughout this range.
Can MAX6250BCSA+T drive a 100µF output capacitor without instability?
Yes, MAX6250BCSA+T is explicitly specified as stable with capacitive loads from 0µF to 100µF across all load currents (0 to ±15mA). This is stated in the Applications Information section and verified in Typical Operating Characteristics (TOC16). No external series resistance or isolation is required, simplifying filtering and transient suppression in sensitive measurement circuits.
Does MAX6250BCSA+T require an external trimming resistor to achieve its ±0.02% initial accuracy?
No, MAX6250BCSA+T achieves ±0.02% initial accuracy at power-up without any external components. The TRIM pin is optional and used only for fine adjustment (±30mV); using it does not degrade the specified tempco or long-term stability. The ±0.02% accuracy is guaranteed as-delivered and applies to the unadjusted output.
What is the typical supply current of MAX6250BCSA+T at +25°C?
The typical supply current of MAX6250BCSA+T is 3.0mA at +25°C and VIN = 10V, as specified in the Electrical Characteristics table for MAX6250 (page 4). Maximum supply current is 3.3mA across the full industrial temperature range (–40°C to +85°C), ensuring predictable power budgeting in low-power systems.
Is MAX6250BCSA+T pin-compatible with other members of the MAX6225/MAX6241/MAX6250 family?
Yes, MAX6250BCSA+T shares identical 8-pin SO package, pinout, and terminal functions with MAX6225 and MAX6241 variants (e.g., MAX6225BCSA+, MAX6241BCSA+). All three feature IN, NR, GND, TRIM, and OUT on pins 2, 3, 4, 5, and 6 respectively, with pins 1/7/8 internally connected and unused-enabling drop-in replacement when only output voltage differs.
