Product details
Overview
LTC2064HMS8#TRPBF from Analog Devices is a dual, zero-drift, micropower operational amplifier in an 8-lead MSOP package, rated for –40°C to 125°C operation. It delivers 2 µA maximum supply current per amplifier, 5 µV max input offset voltage, and 0.02 µV/°C max offset drift - enabling precision signal conditioning in ultra-low-power sensor interfaces such as oxygen sensors and energy-harvesting nodes.
For engineers reviewing the LTC2064HMS8#TRPBF datasheet, LTC2064HMS8#TRPBF pinout, LTC2064HMS8#TRPBF application, or LTC2064HMS8#TRPBF equivalent, key selection criteria include rail-to-rail I/O, integrated EMI filtering (114 dB at 1.8 GHz), shutdown current ≤170 nA, and guaranteed performance across automotive-grade temperature range.
Technical Context
The LTC2064HMS8#TRPBF employs auto-zeroing and chopper-stabilized architecture with 5 kHz internal chopping frequency, achieving near-zero DC errors while maintaining 20 kHz gain-bandwidth product and 3.5 V/ms slew rate. Its self-calibrating circuitry operates continuously without idle tones, suppressing clock feedthrough artifacts even with high-impedance feedback networks.
Input stage uses MOSFETs with bootstrapped biasing to limit input bias current to ≤20 pA (–40°C to 85°C) and ≤100 pA (–40°C to 125°C). The integrated EMI filter rejects RF interference up to 2.4 GHz, and rail-to-rail input/output swing supports operation from 1.7 V to 5.25 V supply.
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 - eliminates need for system-level trimming in µV-level measurement chains. |
| Offset Drift | 0.02 µV/°C max - ensures <100 nV total drift over full –40°C to 125°C range. |
| Input Bias Current | 100 pA max over –40°C to 125°C - permits use of >10 MΩ feedback resistors without significant error. |
| EMI Rejection | 114 dB at 1.8 GHz - suppresses cellular/WiFi interference without external filtering. |
| Shutdown Current | 170 nA max per amplifier - reduces system power by >99% during sleep intervals. |
| Operating Voltage | 1.7 V to 5.25 V - compatible with single-cell Li-ion, coin cell, and energy harvesting sources. |
Pinout & Package
Package: 8-lead MSOP (MS8), 3 mm × 3 mm, exposed pad connected to V–. Thermal resistance θJA = 163°C/W, θJC = 40°C/W.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | +IN A | Noninverting input of Amplifier A - high-impedance node requiring symmetric layout to minimize thermocouple EMF. |
| 2 | –IN A | Inverting input of Amplifier A - connects to feedback network; sensitive to clock feedthrough from high-Z sources. |
| 3 | OUT A | Amplifier A output - rail-to-rail capable; drives loads down to 10 kΩ with <20 mV swing loss. |
| 4 | V– | Negative supply rail - exposed pad must be soldered to PCB ground plane for thermal and noise performance. |
| 5 | V+ | Positive supply rail - requires local 100 nF ceramic bypass capacitor to minimize PSRR degradation. |
| 6 | –IN B | Inverting input of Amplifier B - independent channel; crosstalk to Channel A is –120 dB at 100 kHz. |
| 7 | +IN B | Noninverting input of Amplifier B - matched input structure to Channel A for differential sensing. |
| 8 | SHDN | Shutdown control - logic high ≥1.8 V (referred to V–) enables both amplifiers; floating prohibited. |
Key Features
| Feature | Design Value |
|---|---|
| Zero-drift architecture | Continuous auto-zeroing + chopping eliminates 1/f noise and drift without introducing idle tones. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX40007AUT#T | Single-channel, 900 nA supply current, no shutdown, 10 µV VOS, 0.1 µV/°C drift. | Lacks dual-channel integration and EMI filtering; suited for space-constrained single-sensor nodes only. | Choose when lowest possible quiescent current is critical and dual amplification is unnecessary. |
| AD8628ARZ | Dual-channel, 1.2 mA supply current, no shutdown, 1 µV VOS, 0.005 µV/°C drift, SOIC-8 package. | Higher power negates energy-harvesting use cases; superior drift but incompatible with battery-limited designs. | Choose only for lab-grade instrumentation where power is not constrained and sub-µV stability is mandatory. |
Compared with MAX40007AUT#T and AD8628ARZ, the LTC2064HMS8#TRPBF uniquely balances ultra-low power (2 µA), dual-channel integration, EMI hardening, and automotive-grade temperature range - making it the sole option for compact, battery-operated, field-deployable sensor nodes requiring long-term stability.

FAQ
What is the maximum operating temperature range specified for the LTC2064HMS8#TRPBF?
The LTC2064HMS8#TRPBF is fully specified over the –40°C to 125°C temperature range, with all key parameters - including input offset voltage (5 µV max), offset drift (0.02 µV/°C max), and input bias current (100 pA max) - guaranteed across this extended automotive-grade range. This makes the LTC2064HMS8#TRPBF suitable for under-hood automotive sensors and industrial edge nodes exposed to harsh thermal environments.
How does the LTC2064HMS8#TRPBF achieve EMI immunity without external components?
The LTC2064HMS8#TRPBF integrates an on-die RC EMI filter that provides 114 dB rejection at 1.8 GHz - measured as EMIRR = 20·log(VRF/ΔVOS). This internal filtering eliminates the need for external ferrite beads, LC networks, or shielded enclosures in cellular/WiFi-rich environments, directly reducing bill-of-materials cost and PCB area while maintaining µV-level accuracy.
Can the LTC2064HMS8#TRPBF drive capacitive loads without instability?
Yes - the LTC2064HMS8#TRPBF is stable with capacitive loads up to 100 pF when using a 47 pF compensation capacitor in parallel with the feedback resistor. Its phase margin remains >60° across all tested conditions (CL = 0 pF to 100 pF), and small-signal overshoot stays below 15% at 1.8 V and 5 V supplies. For larger loads, external isolation resistors are recommended.
What is the typical power-up time and charge injection of the LTC2064HMS8#TRPBF during enable?
The LTC2064HMS8#TRPBF powers up in ≤2 ms with ≤20 nC total charge injection at the output - verified across –40°C to 125°C. This low-charge, fast-enable behavior prevents disruptive transients in duty-cycled systems (e.g., wake-on-event sensor nodes), ensuring clean signal acquisition immediately after SHDN pin assertion without post-power-up settling delays.
Does the LTC2064HMS8#TRPBF require special PCB layout considerations for thermocouple error mitigation?
Yes - due to its 0.02 µV/°C drift specification, thermocouple EMFs from dissimilar metal junctions (e.g., copper traces, solder, connectors) can dominate error. Layout best practices for the LTC2064HMS8#TRPBF include symmetric input routing, elimination of sockets/switches in the signal path, matching thermal gradients across +IN/–IN traces, and use of low-EMF solder (e.g., Sn96.5/Ag3.0/Cu0.5).
