Product details
Overview
LTC2063ISC6#TRMPBF from Analog Devices is a single-channel, zero-drift, micropower operational amplifier in a 6-lead SC70 package. It delivers 20kHz bandwidth, 5µV max input offset voltage, 0.02µV/°C max drift, and 2µA max supply current - enabling high-resolution sensor signal conditioning in ultra-low-power systems such as oxygen sensors and energy-harvesting nodes.
For engineers reviewing the LTC2063ISC6#TRMPBF datasheet, LTC2063ISC6#TRMPBF pinout, LTC2063ISC6#TRMPBF application, or LTC2063ISC6#TRMPBF equivalent, this page provides verified specifications, SC70 package terminal mapping, rail-to-rail I/O operation, integrated EMI filtering (114dB at 1.8GHz), and validated alternatives for low-power precision analog design.
Technical Context
The LTC2063ISC6#TRMPBF uses auto-zeroing and chopper stabilization to achieve near-zero DC errors while maintaining continuous-time signal path integrity. Its internal 5kHz chopping frequency is suppressed to eliminate idle tones, and its bootstrapped MOSFET input stage ensures ≤20pA input bias current at 25°C and ≤100pA across –40°C to 125°C.
It features an integrated EMI filter rejecting 114dB at 1.8GHz, rail-to-rail input/output swing, and a dedicated SHDN pin with 1.8V logic-high threshold (referred to V–). Power-up time is 2ms, and shutdown current is 170nA max - optimized for duty-cycled sensor front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 2µA max per amplifier - enables multi-year battery life in wireless sensor nodes. |
| Input Offset Voltage | 5µV max - supports µV-level DC measurement accuracy without calibration. |
| Offset Drift | 0.02µV/°C max - eliminates thermal drift error in unregulated environments. |
| Input Bias Current | 20pA max (–40°C to 85°C) - permits use of >10MΩ feedback resistors for power savings. |
| EMI Rejection | 114dB at 1.8GHz - suppresses cellular/WiFi interference in noisy industrial settings. |
| Operating Voltage | 1.7V to 5.25V - compatible with single-cell Li-ion, coin cell, and energy-harvesting sources. |
| Gain Bandwidth | 20kHz - sufficient for slow-varying sensor outputs (e.g., gas, temperature, pH). |
Pinout & Package
Package: 6-lead plastic SC70 (3.0mm × 1.3mm × 0.9mm), moisture sensitivity level 1, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +IN | Noninverting input | High-impedance node accepting sensor signals up to rail; referenced to V–. |
| V– | Negative supply | Ground or negative rail connection; exposed pad (if present) must be tied to V–. |
| –IN | Inverting input | Feedback node; sensitive to clock feedthrough - requires low-impedance layout. |
| V+ | Positive supply | 1.7V–5.25V input; bypass capacitor required between V+ and V– for stability. |
| SHDN | Shutdown control | Logic-high ≥1.8V enables amplifier; logic-low ≤0.8V disables (170nA IQ). |
| OUT | Amplifier output | Rail-to-rail swing; drives 499kΩ load to within 0.1mV of rails at 1.8V supply. |
Key Features
| Feature | Design Value |
|---|---|
| Zero-drift architecture | Self-calibrating circuitry achieves 5µV max VOS and 0.02µV/°C max drift - no external trimming needed. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC2057IS6#TRMPBF | Lower 1.3µA typical supply current but 10µV max VOS and no integrated EMI filter. | Better for sub-µA always-on monitoring; less suitable for RF-noisy industrial sites. | Choose when lowest possible IQ dominates over EMI immunity and offset spec. |
| AD8531AKSZ-REEL7 | Higher 45µA supply current, 1.5mV max VOS, no shutdown, but wider 3MHz GBW. | Applicable where speed matters more than power - e.g., fast-sampling data loggers. | Choose when bandwidth >100kHz is required and battery life is secondary. |
Compared with LTC2063ISC6#TRMPBF, LTC2057IS6#TRMPBF trades EMI rejection and tighter offset for marginal IQ reduction, while AD8531AKSZ-REEL7 sacrifices micropower operation for higher speed - making LTC2063ISC6#TRMPBF optimal for ultra-low-power, high-precision, RF-immune sensing.

FAQ
What is the maximum supply voltage for the LTC2063ISC6#TRMPBF?
The LTC2063ISC6#TRMPBF has an absolute maximum total supply voltage (V+ to V–) of 5.5V. Its specified operating range is 1.7V to 5.25V - meaning it functions reliably across single-cell lithium (2.7–4.2V), coin cell (1.8–3.0V), and regulated 3.3V/5V rails. Exceeding 5.5V risks permanent damage per Absolute Maximum Ratings.
Does the LTC2063ISC6#TRMPBF require external capacitors for stability?
Yes, the LTC2063ISC6#TRMPBF requires a bypass capacitor between V+ and V– pins, typically 0.1µF ceramic placed as close as possible to the SC70 package. This stabilizes the supply impedance and prevents oscillation, especially under varying load conditions. No compensation capacitor is needed at the output for unity-gain stable operation.
Can the LTC2063ISC6#TRMPBF drive capacitive loads directly?
The LTC2063ISC6#TRMPBF is unity-gain stable but exhibits increasing overshoot with capacitive loads >100pF - reaching ~35% at 1000pF (per Figure 2063 G57/G58). For loads >100pF, isolate with a series resistor (e.g., 10–50Ω) or add a small feedback capacitor (e.g., 2–10pF) to maintain phase margin in precision applications.
How does the SHDN pin behave when left floating?
The SHDN pin of the LTC2063ISC6#TRMPBF must not be left floating. Per the datasheet, floating may cause undefined operation or increased current draw. It should be actively driven to V+ (≥1.8V) for enable or V– (≤0.8V) for shutdown. A pull-up resistor to V+ is acceptable if GPIO control is unavailable, but weak pull-ups risk marginal logic thresholds.
Is the LTC2063ISC6#TRMPBF suitable for thermocouple amplification?
Yes - the LTC2063ISC6#TRMPBF's 5µV max input offset and 0.02µV/°C max drift make it well-suited for thermocouple front-ends, provided thermocouple junctions are minimized and cold-junction compensation is implemented externally. Its low IB (<20pA) avoids voltage errors across high-impedance thermocouple leads, but PCB layout must mitigate Seebeck effects per Application Note.
