Product details
Overview
MAX6241ACSA+T from Maxim Integrated is a precision 4.096V buried-zener voltage reference IC with 1.0ppm/°C temperature coefficient, ±0.02% initial accuracy, and 2.4µVP-P (0.1Hz–10Hz) output noise-designed for high-resolution ADC/DAC biasing in test equipment and industrial control systems.
For engineers reviewing the MAX6241ACSA+T datasheet, MAX6241ACSA+T pinout, MAX6241ACSA+T application, or MAX6241ACSA+T equivalent, this device delivers laboratory-grade stability in an 8-pin SO package with trim-adjustable output, noise-reduction capability, and ±15mA sourcing/sinking for demanding analog signal chains.
Technical Context
The MAX6241ACSA+T employs buried-zener core technology with on-chip temperature compensation to achieve near-zero thermal curvature over 0°C to +70°C. Its low-noise architecture includes dedicated NR pin for external 1µF capacitor filtering and TRIM pin enabling ±24mV (±0.59%) adjustment without degrading tempco.
It operates from 8V to 36V input, maintains stable regulation under capacitive loads up to 100µF, and exhibits excellent transient response (<8µs settling to ±0.01%) and 20ppm/1000h long-term stability-critical for metrology-grade calibration references.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 4.096V ±1mV at +25°C - enables exact 12-bit full-scale alignment in 4.096V-referenced SAR ADCs |
| Tempco (Max) | 1.0ppm/°C - ensures ≤±0.28mV drift over 0°C to +70°C ambient range |
| Initial Accuracy | ±0.02% - guarantees absolute output tolerance of ±0.82mV before trimming |
| Output Noise | 2.4µVP-P (0.1Hz–10Hz) - preserves SNR >110dB in 16-bit data converters |
| Load Regulation | ≤6ppm/mA sourcing - holds output within ±0.025mV across 0–15mA load variation |
| Supply Current | 1.9–2.9mA - supports low-power portable instrumentation with minimal self-heating |
| Long-Term Stability | 20ppm/1000h - ensures <±0.082mV drift per 1000 hours in continuous operation |
Pinout & Package
MAX6241ACSA+T is housed in an 8-pin SO (Small Outline) package compliant with RoHS and JEDEC MS-012 standards. The package features gull-wing leads, 1.27mm pitch, and 5.0mm × 6.2mm body size.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8 | I.C. (Internally Connected) | No external connection required; internal bonding only-must be left unconnected |
| 2 | IN | Positive supply input (8V–36V); requires local 2.2µF bypass capacitor to GND |
| 3 | NR | Noise reduction node; connect 1µF capacitor to GND to reduce wideband noise by >10dB |
| 4 | GND | Analog ground reference; must be star-connected to minimize ground bounce |
| 5 | TRIM | External voltage adjust input; accepts 0–VOUT to shift output ±24mV (±0.59%) |
| 6 | OUT | Precision 4.096V reference output; stable into 0–100µF capacitive loads |
Key Features
| Feature | Design Value |
|---|---|
| Buried-zener core | Delivers lowest 1/f noise and superior long-term stability vs. bandgap references |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF5040IDR | 4.096V, 3ppm/°C max tempco, 3.8µVP-P noise, 10mA max output | Higher noise and looser tempco; requires external buffer for >10mA loads | Lower-cost option where ±0.05% accuracy and 5ppm/°C drift are acceptable |
| ADR444BRZ | 4.096V, 1.5ppm/°C max tempco, 3.5µVP-P noise, 10mA max output | Slightly higher noise and tempco; no NR pin or trim capability | Preferred when ultra-low thermal hysteresis (5ppm) is prioritized over trim flexibility |
Compared with REF5040IDR and ADR444BRZ, the MAX6241ACSA+T offers tighter initial accuracy, lower noise, integrated trim/NR functionality, and higher output drive-making it optimal for metrology-critical designs where board space and calibration simplicity matter.

FAQ
What is the maximum operating temperature range for MAX6241ACSA+T?
The MAX6241ACSA+T is rated for 0°C to +70°C ambient operation ('C' grade). Its electrical specifications-including 1.0ppm/°C tempco and ±0.02% initial accuracy-are guaranteed across this full range. Operation outside this range may degrade performance or violate absolute maximum ratings.
Can MAX6241ACSA+T drive a 10µF output capacitor without instability?
Yes. The MAX6241ACSA+T is explicitly characterized and guaranteed stable with output capacitance from 0µF to 100µF across all load currents. No series isolation resistor is needed-unlike many bandgap references-making it ideal for low-noise applications requiring heavy local bypassing.
How does the NR pin reduce noise in MAX6241ACSA+T?
The NR pin connects to an internal noise-filtering network. Adding a 1µF capacitor from NR to GND attenuates wideband noise-particularly above 10Hz-by up to 10dB. This complements the inherent 1/f noise suppression of the buried-zener core, reducing total 0.1Hz–10Hz noise to 2.4µVP-P.
What is the trim-adjustment range of MAX6241ACSA+T?
The TRIM pin allows ±24mV (±0.59%) adjustment of the 4.096V output using a 10kΩ potentiometer between OUT and GND. This corresponds to ±0.6% full-scale range and does not affect temperature coefficient or long-term stability-enabling precise system-level calibration.
Is MAX6241ACSA+T pin-compatible with other MAX62xx variants?
Yes. All MAX6225/MAX6241/MAX6250 devices share identical 8-pin SO pinout and terminal functions. The MAX6241ACSA+T can replace MAX6225ACSA+T or MAX6250ACSA+T on the same PCB-only the output voltage differs (2.5V/4.096V/5.0V), with identical tempco, noise, and drive specs.
