Analog Devices Inc. LT1460BIN8-10#PBF

Overview

LT1460BIN8-10#PBF from Analog Devices (formerly Linear Technology) is an industrial-grade, micropower precision series voltage reference delivering a stable 10.000 V output with ±0.10% initial accuracy and 10 ppm/°C max temperature coefficient over –40°C to +85°C. It supplies up to 20 mA, features reverse battery protection, requires no output capacitor, and operates with only 0.9 V input-output differential-ideal for low-headroom precision regulator and data converter biasing applications.

For engineers reviewing the LT1460BIN8-10#PBF datasheet, LT1460BIN8-10#PBF pinout, LT1460BIN8-10#PBF application, or LT1460BIN8-10#PBF equivalent, key selection criteria include its guaranteed 10 ppm/°C drift over full industrial temperature range, 190–360 µA supply current at 10 V output, stability with capacitive loads, and compatibility with 8-lead PDIP packaging for through-hole prototyping and legacy industrial designs.

Technical Context

The LT1460BIN8-10#PBF employs curvature-compensated bandgap architecture to achieve low thermal drift without external trimming. Its internal thin-film resistor network is laser-trimmed for ±0.10% output accuracy across the industrial temperature range.

It operates as a three-terminal series reference with active pass element, enabling high load current capability (20 mA) while maintaining excellent line regulation (10–35 ppm/V) and load regulation (20–140 ppm/mA), and eliminating the power-wasting idle current required by shunt references.

Key Specifications

Pinout & Package

FAQ

What is the maximum load current supported by the LT1460BIN8-10#PBF?

The LT1460BIN8-10#PBF supports up to 20 mA of continuous sourcing current while maintaining specified accuracy and regulation. Short-circuit output current is rated at 40 mA. Load regulation remains within ±140 ppm/mA up to 20 mA at 0°C to 70°C, and ±100 ppm/mA over the full –40°C to +85°C range, ensuring stable 10 V output under dynamic loading typical in ADC reference and op-amp bias applications.

Does the LT1460BIN8-10#PBF require an output capacitor for stability?

No, the LT1460BIN8-10#PBF does not require an output capacitor for stability-it is explicitly designed to remain stable with capacitive loads ranging from 0 µF to 1 µF. This eliminates capacitor-related drift, aging, and board space constraints. However, adding ≥0.1 µF may improve transient response in high-current step applications, and a small series resistor (e.g., 2 Ω) can suppress ringing when using ≥1 µF output capacitance.

What is the minimum input voltage required for proper operation of the LT1460BIN8-10#PBF?

The LT1460BIN8-10#PBF requires a minimum input-to-output differential voltage of 0.9 V at zero load and 1.4 V at 10 mA load. Therefore, for reliable 10.000 V output, the minimum input voltage is 10.9 V (at I_OUT = 0) and 11.4 V (at I_OUT = 10 mA). Absolute maximum input voltage is 30 V, and reverse input voltage tolerance is –15 V-enabling robust operation in 12 V systems with margin.

How does the LT1460BIN8-10#PBF compare to shunt references in terms of power efficiency?

Unlike shunt references that waste power by sinking full-load current continuously, the LT1460BIN8-10#PBF draws only 190–360 µA quiescent current regardless of load, scaling dynamically with demand. At zero load, it dissipates <2 mW from a 12 V supply-extending battery life significantly. When delivering 20 mA, total dissipation remains efficient (~200 mW), avoiding the fixed high-idle losses inherent to shunt topologies.

Is the LT1460BIN8-10#PBF pin-compatible with other members of the LT1460 family?

Yes, all LT1460 variants in the N8 (8-lead PDIP) package-including LT1460BIN8-2.5#PBF, LT1460BIN8-5#PBF, and LT1460BIN8-10#PBF-share identical pinout: Pin 1 = VIN, Pin 3 = GND, Pin 8 = VOUT, and Pins 2/4–7 = DNC. This allows drop-in replacement across output voltages in existing DIP-based designs, provided input supply and load requirements are verified per variant specification.
