Analog Devices Inc. LT1460BIN8-5#PBF

Overview

LT1460BIN8-5#PBF from Analog Devices (formerly Linear Technology) is an industrial-grade micropower precision series voltage reference delivering a stable 5.000 V output with ±0.10% initial accuracy, 10 ppm/°C max temperature coefficient over –40°C to +85°C, and 20 mA sourcing capability. It operates with as little as 0.9 V input-output differential and requires no output capacitor-enabling use in low-power, space-constrained precision regulator and data converter biasing applications.

For engineers reviewing the LT1460BIN8-5#PBF datasheet, LT1460BIN8-5#PBF pinout, LT1460BIN8-5#PBF application, or LT1460BIN8-5#PBF equivalent, key selection considerations include its guaranteed industrial temperature range, low 175 µA typical supply current at 5 V output, reverse battery protection, and stability with capacitive loads up to 1 µF without external compensation.

Technical Context

The LT1460BIN8-5#PBF employs curvature-compensated bandgap architecture to achieve low thermal drift and high initial accuracy. Its internal thin-film resistor trimming enables ±0.10% output tolerance across the full –40°C to +85°C range, with line regulation of 10–35 ppm/V and load regulation as low as 20 ppm/mA at 20 mA.

Unlike shunt references, it draws only 175 µA typical supply current while delivering up to 20 mA output-eliminating idle current waste and enabling extended battery life. It features intrinsic reverse-battery protection and remains stable with 0–1 µF output capacitance, removing the need for layout-sensitive compensation networks.

Key Specifications

Pinout & Package

LT1460BIN8-5#PBF is housed in an 8-lead plastic DIP (N8) package with standard through-hole mounting and 0.3-inch body width. Pin 1 is VIN, Pin 2 is DNC (internally connected, no external connection), Pin 3 is DNC, Pin 4 is GND, Pin 5 is DNC, Pin 6 is DNC, Pin 7 is VOUT, Pin 8 is DNC. All DNC pins are internally connected and must remain unconnected externally.

FAQ

What is the maximum operating temperature range for the LT1460BIN8-5#PBF?

The LT1460BIN8-5#PBF is specified for continuous operation from –40°C to +85°C, with temperature coefficient and output accuracy guaranteed across this full industrial range. Its 10 ppm/°C max TC and ±0.10% initial error apply at all temperatures within this span, making it suitable for factory-floor and outdoor embedded systems.

Does the LT1460BIN8-5#PBF require an output capacitor for stability?

No, the LT1460BIN8-5#PBF is inherently stable with 0–1 µF capacitive loads and does not require an external output capacitor. This eliminates associated BOM cost, PCB area, and potential settling-time degradation-particularly valuable in fast-response data acquisition and compact portable designs.

What is the minimum input voltage needed for the LT1460BIN8-5#PBF to regulate at 5 V?

The LT1460BIN8-5#PBF requires a minimum input-to-output differential of 0.9 V. To deliver its nominal 5.000 V output, VIN must be ≥5.9 V. At IOUT = 10 mA, the dropout increases to 1.3–1.4 V, so VIN ≥6.3 V is recommended for full-load operation.

How does reverse battery protection work in the LT1460BIN8-5#PBF?

The LT1460BIN8-5#PBF contains internal circuitry that blocks conduction when VIN is reversed (down to –15 V). No current flows into the device, preventing latch-up, junction damage, or system-level fault propagation-critical for field-serviceable battery compartments and automotive jump-start scenarios.

Can the LT1460BIN8-5#PBF drive a 20 mA load while maintaining its specified accuracy?

Yes-the LT1460BIN8-5#PBF is rated for 20 mA sourcing with guaranteed load regulation of ≤140 ppm/mA (≤0.7 mV total shift from 0 to 20 mA). Combined with its ±0.10% initial accuracy and 10 ppm/°C TC, it maintains full-spec performance across its entire output current range.
