Product details
Overview
LTC2063IS5#TRPBF from Analog Devices is a single-channel, zero-drift, micropower operational amplifier in a 5-lead TSOT-23 package. It delivers 2 µA maximum supply current, 5 µV max input offset voltage, and 0.02 µV/°C max offset drift - enabling high-resolution sensor signal conditioning in ultra-low-power systems such as oxygen sensors and energy-harvesting nodes.
For engineers reviewing the LTC2063IS5#TRPBF datasheet, LTC2063IS5#TRPBF pinout, LTC2063IS5#TRPBF application, or LTC2063IS5#TRPBF equivalent, this page provides verified specifications, real-world use cases, validated alternatives, and supply-chain support for portable instrumentation, gas detection, and low-power current sensing designs.
Technical Context
The LTC2063IS5#TRPBF employs auto-zeroing and chopper stabilization to achieve sub-microvolt offset and near-zero drift over temperature. Its internal 5 kHz chopping frequency is suppressed to minimize clock feedthrough, and integrated EMI filtering delivers 114 dB rejection at 1.8 GHz.
It operates from 1.7 V to 5.25 V, supports rail-to-rail input and output, and features a dedicated SHDN pin with logic thresholds referenced to V– (1.8 V high, 0.8 V low). Power-up time is 2 ms, and shutdown current is ≤170 nA per amplifier across –40°C to 85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 2 µA max per amplifier - enables multi-year battery life in duty-cycled wireless sensors. |
| Input Offset Voltage | 5 µV max - ensures <1 µV error contribution in precision bridge or thermocouple amplifiers. |
| Offset Drift | 0.02 µV/°C max - maintains calibration stability over industrial temperature range without recalibration. |
| Input Bias Current | 30 pA max (–40°C to 85°C) - allows use of >10 MΩ feedback resistors without significant DC error. |
| EMI Rejection | 114 dB at 1.8 GHz - suppresses cellular/WiFi interference in noisy industrial or medical environments. |
| Shutdown Current | 170 nA max - reduces system power by >90% during sleep cycles in energy-harvesting applications. |
| Gain Bandwidth | 20 kHz - sufficient for DC–10 kHz sensor signals including O₂, CO, and temperature transducers. |
Pinout & Package
Package: 5-lead plastic TSOT-23 (3.0 mm × 1.6 mm × 0.8 mm), exposed pad optional, θJA = 215°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 OUT | Amplifier output | Rail-to-rail swing (±0.005 V from rails at 499 kΩ load) - drives ADC inputs or low-power comparators directly. |
| 2 V– | Negative supply | Reference node for SHDN threshold and input common-mode range - must be bypassed with 100 nF capacitor. |
| 3 +IN | Noninverting input | High-impedance MOSFET input (≤30 pA bias) - connects to high-Z sensors (e.g., electrochemical cells) without loading. |
| 4 –IN | Inverting input | Matches +IN in bias and capacitance (3.3 pF diff, 3.5 pF cm) - critical for balanced noise rejection in differential configurations. |
| 5 V+ | Positive supply | Accepts 1.7–5.25 V - enables direct operation from single Li-ion, coin cell, or harvested energy sources. |
Key Features
| Feature | Design Value |
|---|---|
| Zero-drift architecture | Self-calibrating circuitry eliminates 1/f noise and drift - maintains µV-level accuracy over time and temperature. |
| Integrated EMI filter | 114 dB rejection at 1.8 GHz - prevents RF rectification errors in unshielded PCB layouts near wireless modules. |
| Low-charge power-up | Minimal output transient during enable - avoids saturation and settling delays in duty-cycled sensor front-ends. |

FAQ
What is the maximum supply voltage for the LTC2063IS5#TRPBF?
The LTC2063IS5#TRPBF has an absolute maximum total supply voltage (V+ to V–) of 5.5 V. Its specified operating range is 1.7 V to 5.25 V, with guaranteed performance across –40°C to 85°C. Exceeding 5.5 V risks permanent damage per Absolute Maximum Ratings.
Does the LTC2063IS5#TRPBF support rail-to-rail input and output operation?
Yes, the LTC2063IS5#TRPBF supports rail-to-rail input and output. Input common-mode range extends from (V–) – 0.1 V to (V+) + 0.1 V, and output swing reaches within 0.15 mV of V+ and 0.1 mV of V– at 499 kΩ load - enabling full utilization of low-voltage supplies like 1.8 V or 3.3 V.
How does the SHDN pin function on the LTC2063IS5#TRPBF?
The SHDN pin on the LTC2063IS5#TRPBF is referenced to V–. It asserts shutdown when pulled to V– (logic low ≤0.8 V), reducing supply current to ≤170 nA. It enables the amplifier when pulled to V+ (logic high ≥1.8 V). Floating the pin is not recommended - tie to V+ or V– via a resistor for deterministic behavior.
What is the typical input bias current of the LTC2063IS5#TRPBF at room temperature?
The typical input bias current of the LTC2063IS5#TRPBF is 3 pA at 25°C and 1.8 V supply. Over the full –40°C to 85°C range, it remains ≤30 pA - enabling use with feedback networks up to 100 MΩ while maintaining <0.3 µV bias-induced offset error.
Is the LTC2063IS5#TRPBF suitable for high-EMI environments like industrial IoT gateways?
Yes, the LTC2063IS5#TRPBF integrates an on-chip EMI filter delivering 114 dB rejection at 1.8 GHz - verified per manufacturer test data. This suppresses rectified RF interference that would otherwise manifest as DC offset shifts in sensitive sensor front-ends, making it suitable for deployment near cellular, WiFi, or Bluetooth radios without additional shielding.
