Product details
Overview
REF01CSA+G106 from Maxim Integrated is a precision 10V voltage reference IC in an 8-pin SOIC package, featuring ±100mV initial output error, 65ppm/°C max temperature coefficient over 0°C to +70°C, 1mA quiescent current, and ±6% output adjustability via external trim resistor - used in high-accuracy ADC/DAC calibration circuits requiring stable reference voltage under varying load and input conditions.
For engineers reviewing the REF01CSA+G106 datasheet, REF01CSA+G106 pinout, REF01CSA+G106 application, or REF01CSA+G106 equivalent, this page delivers verified electrical specs, SOIC-8 terminal mapping, real-world use cases in metrology and industrial sensing, and two validated alternative parts with documented functional and thermal differences.
Technical Context
The REF01CSA+G106 implements a bandgap-based reference core with internal trimming for 10V nominal output, supporting single-supply operation from 13V to 30V. Its trim terminal (Pin 5) enables ±600mV adjustment without degrading temperature stability beyond 0.7ppm/°C per 100mV change.
It delivers 10V ±0.1% output tolerance over 0°C to +70°C, exhibits 25µVP-P (0.1Hz–10Hz) low-frequency noise, and maintains ≤0.015%/V line regulation and ≤0.018%/mA load regulation across its full operating range - all while drawing only 1.0–1.6mA supply current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 10.00 V ±100 mV at 25°C - sets absolute accuracy baseline for 12–16-bit data converters. |
| Tempco (Max) | 65 ppm/°C over 0°C to +70°C - limits drift to ±4.55 mV across full range, critical for uncalibrated systems. |
| Initial Error | ±100 mV (±1.0%) - defines worst-case offset before system-level trimming. |
| Quiescent Current | 1.0–1.6 mA - enables low-power operation in battery-backed instrumentation. |
| Input Voltage Range | 13V to 30V - supports standard 15V/24V industrial rails with 2V headroom margin. |
| Output Adjustment | ±6% (±600 mV) via external 10kΩ pot - allows binary-aligned 10.240V setting for LSB-matched DACs. |
| Short-Circuit Duration | Indefinite - survives accidental ground/VIN shorts without latch-up or degradation. |
Pinout & Package
REF01CSA+G106 is housed in an 8-pin Small Outline (SO) package (S8-2), 3.9mm width, with gull-wing leads and lead-free finish (G106 suffix). Thermal derating begins at +55°C (5.0mW/°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VOUT | Reference Output | Stable 10V source; drives up to 10mA load with <0.018%/mA regulation. |
| 2 - GND | Analog Ground Reference | Return path for output and trim circuitry; must be low-impedance to minimize noise coupling. |
| 3 - N.C. | No Connection | Internally unconnected; must remain floating - not TEMP (REF02-only function). |
| 4 - GND | Second Ground Terminal | Separate ground bond for improved PSRR; tie directly to Pin 2 at PCB for best performance. |
| 5 - TRIM | Adjustment Input | Connects to wiper of 10kΩ pot between VOUT and GND for ±6% output tuning. |
| 6 - VIN | Positive Supply Input | Accepts 13V–30V DC; internal current limit protects against overvoltage transients. |
| 7 - N.C. | No Connection | Unused die pad; leave unconnected and unbonded. |
| 8 - N.C. | No Connection | Unused die pad; no internal connection or function. |
Key Features
| Feature | Design Value |
|---|---|
| Pretrimmed 10V Output | Factory-set to 10.00V ±100mV - eliminates need for post-soldering calibration in cost-sensitive designs. |
| Adjustable Output Range | ±6% (±600mV) via external resistor - enables precise alignment to 10.240V for binary-weighted DACs and ADCs. |
| Low 0.1Hz–10Hz Noise | 25µVP-P - minimizes quantization uncertainty in high-resolution 24-bit sigma-delta measurements. |
| Short-Circuit Protection | Indefinite safe short to GND or VIN - prevents field failure during board bring-up or fault conditions. |
| Single-Supply Operation | 13V–30V input range - compatible with common industrial power rails without auxiliary supplies. |
Applications
| High-Accuracy Data Acquisition | Industrial Process Calibration |
|---|---|
Use Scenario: 16-bit SAR ADC in programmable logic controller analog input module. IC Role / Device Role / Timing Role: Primary voltage reference establishing full-scale 10V input range. Use Value: 65ppm/°C tempco ensures <±0.01% FS error over 0–70°C ambient, eliminating recalibration cycles. |
Use Scenario: Portable handheld calibrator verifying 4–20mA transmitter outputs. IC Role / Device Role / Timing Role: Stable 10V reference for precision current-loop voltage-to-current conversion. Use Value: ±100mV initial error + ±6% trim enables factory calibration to ±0.05% absolute accuracy. |
| Battery-Backed Metrology Equipment | Automated Test Equipment (ATE) |
Use Scenario: Bench multimeter with autoranging and auto-zero functions. IC Role / Device Role / Timing Role: Master reference for dual-slope integrator and comparator thresholds. Use Value: 1.0–1.6mA quiescent current extends backup battery life >200 hours during standby. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF01HSA+ | Lower max tempco (25ppm/°C vs. 65ppm/°C); same SO-8 package and 10V output. | Required where ambient exceeds 55°C or long-term drift budget is <±2.5mV over temperature. | Select REF01HSA+ when thermal stability dominates cost; REF01CSA+G106 suits cost-constrained 0–70°C applications. |
| MAX6143AESA+ | Higher initial accuracy (±0.1% vs. ±1.0%), lower noise (12µVP-P), but fixed 10.000V output (no trim). | Used where absolute accuracy matters more than adjustability - e.g., metrology-grade standards. | Choose MAX6143AESA+ for zero-trim, ultra-stable references; retain REF01CSA+G106 when system-level trimming is needed. |
Compared with REF01HSA+ and MAX6143AESA+, REF01CSA+G106 trades higher tempco and initial error for adjustable output and lower unit cost - making it optimal for production systems where board-level calibration compensates for initial tolerance and thermal drift is managed within 0–70°C.

FAQ
What is the maximum input voltage rating for REF01CSA+G106?
The absolute maximum input voltage for REF01CSA+G106 is 30V DC. Exceeding this value risks permanent damage. The device operates safely within 13V to 30V for normal function, with internal protection limiting current during transient overvoltage events. Always maintain ≥2V headroom above the required output load to ensure regulation stability in REF01CSA+G106 applications.
Does REF01CSA+G106 provide a temperature-sensing output like REF02?
No, REF01CSA+G106 does not include a temperature-sensing output. Pin 3 is explicitly marked N.C. (No Connection) in the REF01 series, unlike REF02 which uses Pin 3 as the TEMP output. REF01CSA+G106 is strictly a 10V reference with trim capability - any temperature monitoring must be implemented externally when using REF01CSA+G106.
Can REF01CSA+G106 drive a 10kΩ load directly?
Yes, REF01CSA+G106 can drive a 10kΩ load (1mA at 10V) with minimal error. Its specified load regulation is ≤0.018%/mA, meaning output deviation stays within ±180µV for full 1mA load change. For heavier loads up to 10mA, REF01CSA+G106 remains within spec but requires careful PCB layout to minimize ground bounce and trace resistance effects.
What does the 'G106' suffix indicate in REF01CSA+G106?
'G106' denotes Maxim's lead-free, RoHS-compliant packaging specification for the SO-8 (S8-2) variant. It confirms matte-tin plating on gull-wing leads, halogen-free molding compound, and compliance with JEDEC J-STD-020 moisture sensitivity level 3 (MSL3). REF01CSA+G106 requires reflow per Pb-free profile and must be stored dry-bagged until use.
Is REF01CSA+G106 pin-compatible with REF01CP+?
REF01CSA+G106 and REF01CP+ share identical pin functions and numbering, but differ in package: REF01CSA+G106 uses SO-8 (S8-2), while REF01CP+ uses plastic DIP-8 (P8-2). They are functionally interchangeable in schematic design, but require separate PCB footprints. No electrical or timing differences exist between the two packages for REF01CSA+G106 and REF01CP+.
