Product details
Overview
LTC2067HMS8#PBF from Analog Devices is a dual, zero-drift, rail-to-rail input/output operational amplifier optimized for ultra-low-power precision sensing. It delivers 10µA maximum supply current per amplifier, 5µV max input offset voltage, and 0.02µV/°C max offset drift across –40°C to 125°C - enabling high-resolution current sensing and sensor signal conditioning in energy-constrained wireless sensor nodes.
For engineers reviewing the LTC2067HMS8#PBF datasheet, LTC2067HMS8#PBF pinout, LTC2067HMS8#PBF application, or LTC2067HMS8#PBF equivalent, key selection criteria include shutdown current (≤170nA), input bias current (≤35pA at 25°C, ≤150pA over full temperature range), EMI rejection (90dB at 1.8GHz), and MS8 package compatibility with space-limited PCB layouts.
Technical Context
The LTC2067HMS8#PBF employs auto-zeroing and chopper-stabilized architecture with 25kHz internal chopping frequency to eliminate 1/f noise and minimize DC errors. Its self-calibrating circuitry maintains precision without external trimming while supporting operation from 1.7V to 5.25V single-supply or ±0.85V to ±2.625V dual-supply configurations.
Each amplifier features integrated EMI filtering, low-charge power-up behavior for duty-cycled systems, and rail-to-rail output swing within 0.15mV of V+ and 0.1mV of V– at 499kΩ load - critical for maintaining dynamic range in low-voltage, high-impedance feedback networks.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision micropower op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC2063IMS8#PBF | Single-channel version; identical specs except for channel count and package marking | Used where only one amplifier is needed - saves board area but lacks dual-channel correlation | Select when design requires only one precision amp and space is constrained |
| AD8538ARMZ | Higher 25µA supply current; 10µV max VOS; no integrated EMI filter; SOIC-8 package | Suitable for less RF-noisy environments; larger footprint limits high-density layouts | Choose if cost sensitivity outweighs EMI robustness and ultra-low IQ requirements |

FAQ
What is the maximum operating temperature range for the LTC2067HMS8#PBF?
The LTC2067HMS8#PBF is specified for continuous operation from –40°C to +125°C ambient temperature. This H-grade qualification makes it suitable for under-hood automotive, industrial motor control, and outdoor IoT deployments where thermal extremes are expected. The device maintains all key specifications - including 5µV max input offset and 10µA max supply current - across this full range.
Does the LTC2067HMS8#PBF require external capacitors on its power pins?
Yes, the LTC2067HMS8#PBF requires a minimum 100nF ceramic bypass capacitor placed between V+ and V– pins, as close as possible to the device. This is mandatory to ensure stability, suppress supply noise, and maintain specified PSRR (108dB) and CMRR (111dB). Failure to include proper bypassing may cause oscillation or degraded precision performance, especially in high-impedance sensor circuits.
How does the SHDN pin function on the LTC2067HMS8#PBF?
The SHDN pin on the LTC2067HMS8#PBF is referenced to V–. Driving it to ≥1.8V (logic high) enables both amplifiers; pulling it to ≤0.8V (logic low) places both amplifiers into shutdown mode, reducing total supply current to ≤170nA per amplifier. The pin draws ≤150nA current and must not be left floating - tie to V– or V+ through appropriate logic interface.
Can the LTC2067HMS8#PBF drive capacitive loads directly?
The LTC2067HMS8#PBF is stable driving up to 100pF capacitive load with 100% phase margin. For loads >100pF, a series isolation resistor (typically 10Ω–100Ω) should be added between the output and capacitance to prevent peaking or oscillation. This is critical in applications like anti-aliasing filter stages or long PCB traces feeding ADC inputs.
Is the LTC2067HMS8#PBF RoHS compliant and lead-free?
Yes, the LTC2067HMS8#PBF is RoHS and WEEE compliant, with lead-free finish (Pb-free) on all terminals. The "#PBF" suffix explicitly denotes compliance with EU Directive 2011/65/EU. It meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) and is qualified for reflow soldering per IPC/JEDEC J-STD-020 standards.
