Product details
Overview
LT1460CCMS8-10#TRPBF from Analog Devices (formerly Linear Technology) is a micropower precision series voltage reference delivering 10.000 V ±0.10% initial accuracy, 20 ppm/°C max temperature coefficient over 0°C to 70°C, and stable operation with up to 20 mA output current. It features no required output capacitor, reverse battery protection, and 0.9 V minimum input-output differential-making it ideal for portable instrumentation and high-accuracy ADC/DAC biasing.
For engineers reviewing the LT1460CCMS8-10#TRPBF datasheet, LT1460CCMS8-10#TRPBF pinout, LT1460CCMS8-10#TRPBF application, or LT1460CCMS8-10#TRPBF equivalent, this page provides verified package mapping (8-lead MSOP), confirmed thermal regulation (2.5 ppm/mW), load regulation (140 ppm/mA at 20 mA), supply current (270 µA max), and real-world stability data including hysteresis (50 ppm) and long-term drift (40 ppm/√kHr).
Technical Context
The LT1460CCMS8-10#TRPBF uses curvature-compensated bandgap architecture to achieve low temperature drift while maintaining micropower operation. Its internal thin-film resistor trimming enables 0.10% output voltage accuracy across the commercial temperature range without external calibration.
It operates as a three-terminal series reference with VIN, VOUT, and GND pins-requiring only 0.9 V headroom above output voltage and delivering regulated 10 V with line regulation of 35 ppm/V (at VIN ≥ VOUT + 2.5 V) and load regulation of 140 ppm/mA (at IOUT = 20 mA, 0°C to 70°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 10.000 V ±0.10% (9.990 V to 10.010 V at 25°C; ensures precise full-scale reference for 16-bit+ converters) |
| Temp Coefficient | 20 ppm/°C max (0°C to 70°C; supports stable performance in uncontrolled ambient environments) |
| Supply Current | 270 µA max (enables >1-year battery life in 10 µA sleep-mode systems with intermittent 10 mA bursts) |
| Dropout Voltage | 0.9 V min (allows operation from 10.9 V supply; reduces heat dissipation vs shunt alternatives) |
| Output Current | 20 mA sourcing capability (drives multiple op-amp inputs or SAR ADC references without buffering) |
| Line Regulation | 35 ppm/V (VOUT + 2.5 V ≤ VIN ≤ 20 V; maintains <35 µV/V supply ripple rejection) |
| Load Regulation | 140 ppm/mA at 20 mA (≤2.8 mV shift from no-load to full-load; critical for ratiometric sensor interfaces) |
Pinout & Package
LT1460CCMS8-10#TRPBF is housed in an 8-lead MSOP (MS8) package with exposed pad (θJA = 250°C/W). Pin 1 is VIN, Pin 2 is VOUT, Pin 3 is GND, and Pins 4–8 are internally connected no-connects-external circuitry must not be attached to these terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VIN) | Input Supply Terminal | Accepts 10.9 V to 30 V input; reverse voltage rating –15 V protects against battery misconnection |
| 2 (VOUT) | Regulated Output Terminal | Delivers stable 10.000 V; stable with 0–1 µF capacitive loads-no compensation required |
| 3 (GND) | Reference Ground Terminal | Low-impedance return path; must be routed with minimal trace inductance for noise-sensitive applications |
| 4–8 (DNC) | Internally Connected No-Connect | Not bonded; floating electrically-must remain unconnected per datasheet to avoid parametric shift |
Key Features
| Feature | Design Value |
|---|---|
| No output capacitor required | Enables space-constrained PCB layouts and eliminates capacitor aging effects on long-term stability |
| Reverse battery protection | Zero conduction at –15 V input prevents damage during field servicing or battery replacement |
| 20 mA output drive | Sufficient to directly power multiple precision op-amps or high-resolution ADC references without buffer stages |
| 0.9 V dropout voltage | Reduces power loss by >50% vs comparable references requiring ≥1.5 V headroom at 10 V output |
| 40 ppm/√kHr long-term stability | Ensures <100 ppm total drift over 10 years in industrial instrumentation-critical for metrology-grade devices |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF5010IDR | 10 ppm/°C max tempco, 0.05% initial accuracy, 3.8 mA supply current, SOIC-8 package | Higher accuracy and lower drift-but 14× higher quiescent current limits battery life | Select REF5010IDR when ultra-low drift (<5 ppm/°C) is mandatory and power budget permits >3 mA continuous draw |
| ADR4510BRZ | 3 ppm/°C max tempco, 0.02% initial accuracy, 950 µA supply current, SOIC-8 package | Superior stability and noise performance-but requires 1 µF output capacitor and lacks reverse-battery protection | Select ADR4510BRZ for lab-grade metrology where board space allows capacitor placement and input polarity is guaranteed |
Compared with REF5010IDR and ADR4510BRZ, the LT1460CCMS8-10#TRPBF trades absolute drift performance for micropower operation and robustness-delivering 20 ppm/°C drift at 270 µA versus 10 ppm/°C at 3.8 mA or 3 ppm/°C at 950 µA-making it optimal for portable, cost-sensitive, or fault-tolerant designs where <0.1% accuracy suffices.

FAQ
What is the maximum output current capability of the LT1460CCMS8-10#TRPBF?
The LT1460CCMS8-10#TRPBF delivers up to 20 mA of sourcing current while maintaining specified accuracy and regulation. This is confirmed in the Electrical Characteristics table (page 6) under "Output Current" with short-circuit rating of 40 mA. The 20 mA limit ensures thermal regulation remains within 2.5 ppm/mW and load regulation stays at 140 ppm/mA across the full 0°C to 70°C range.
Does the LT1460CCMS8-10#TRPBF require an output capacitor for stability?
No, the LT1460CCMS8-10#TRPBF is explicitly designed to be stable with zero output capacitance and remains stable with up to 1 µF capacitive loads-no external capacitor is required. This is stated in the Features section ("No Output Capacitor Required") and verified in Typical Performance Characteristics (Figures G09, G21, G32), which show stable transient response and impedance profiles across CL = 0 to 1 µF.
What is the temperature coefficient specification for the LT1460CCMS8-10#TRPBF?
The LT1460CCMS8-10#TRPBF has a maximum temperature coefficient of 20 ppm/°C over the 0°C to 70°C commercial temperature range. This value is listed in the "Available Options" table (page 4) for LT1460CCMS8 grade and confirmed in the Electrical Characteristics table (page 5) under "Output Voltage Temperature Coefficient" for CCMS8 variants.
Can the LT1460CCMS8-10#TRPBF survive reverse battery connection?
Yes-the LT1460CCMS8-10#TRPBF features built-in reverse battery protection and will not conduct current at –15 V input, preventing damage during incorrect battery installation. This is documented in the Features list ("Reverse Battery Protection") and Absolute Maximum Ratings (page 2), where reverse voltage is specified as –15 V with zero conduction implied by absence of reverse current spec.
What is the minimum input-to-output voltage differential for the LT1460CCMS8-10#TRPBF?
The LT1460CCMS8-10#TRPBF requires a minimum input-to-output differential of 0.9 V at zero load current, increasing to 1.4 V at 10 mA output. This dropout specification is found in the Electrical Characteristics table (page 6) under "Dropout Voltage" and is validated in Figure G01 (page 8), showing functional regulation down to VIN = VOUT + 0.9 V across temperature.
