Product details
Overview
LTC2067HDD#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, 0.02µV/°C max offset drift, and 150pA max input bias current over –40°C to 125°C - enabling high-resolution current sensing and sensor signal conditioning in energy-constrained wireless sensor nodes.
For engineers reviewing the LTC2067HDD#PBF datasheet, LTC2067HDD#PBF pinout, LTC2067HDD#PBF application, or LTC2067HDD#PBF equivalent, key selection criteria include shutdown current (≤170nA), EMI rejection (90dB at 1.8GHz), 1.7V–5.25V supply range, and guaranteed H-grade temperature performance up to 125°C.
Technical Context
The LTC2067HDD#PBF employs auto-zeroing and chopper-stabilized architecture with 25kHz internal chopping frequency to eliminate 1/f noise and achieve sub-µV offset stability. Its integrated EMI filter provides 90dB rejection at 1.8GHz, critical for operation in noisy RF environments such as industrial IoT gateways.
It features a dedicated SHDN pin referenced to V–, with logic-high threshold ≥1.8V and logic-low ≤0.8V, enabling low-charge power-up in duty-cycled systems. The dual-channel design supports independent channel shutdown and exhibits <–100dB crosstalk at 1MHz between adjacent channels.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 10µA max per amplifier - enables multi-year battery life in coin-cell-powered sensors |
| Input Offset Voltage | ±5µV max - supports µV-level DC measurement accuracy without calibration |
| Offset Drift | ±0.02µV/°C max - ensures stable baseline over wide industrial temperature range |
| Input Bias Current | 150pA max (–40°C to 125°C) - permits use of MΩ-range feedback resistors for power savings |
| EMI Rejection | 90dB at 1.8GHz - suppresses cellular/WiFi interference in compact PCB layouts |
| Shutdown Current | 170nA max per amplifier - reduces system standby power by >99% vs active mode |
| Gain Bandwidth | 100kHz - sufficient for DC–10kHz sensor signals including thermocouples and gas sensors |
Pinout & Package
The LTC2067HDD#PBF is housed in a 10-lead (3mm × 3mm) plastic DFN package with exposed pad connected to V–. Thermal resistance θJA = 43°C/W enables operation at full spec without heatsinking in ambient up to 85°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 V+ | Positive supply rail | Accepts 1.7V–5.25V; requires local 100nF bypass to V– |
| 2 OUTA | Amplifier A output | Rail-to-rail swing; drives ≥10kΩ load with <20mV error |
| 3 –INA | Inverting input A | High-impedance node; sensitive to layout-induced thermocouple errors |
| 4 +INA | Noninverting input A | Matched to –INA for common-mode rejection; requires symmetric routing |
| 5 V– | Negative supply rail | Reference for SHDN pin; exposed pad must connect to this net |
| 6 OUTB | Amplifier B output | Independent output; supports dual-sensor or differential drive |
| 7 –INB | Inverting input B | Electrically isolated from Channel A; crosstalk <–100dB at 1MHz |
| 8 +INB | Noninverting input B | Matched pair with –INB; same layout rules apply as Channel A |
| 9 SHDN | Shutdown control | Active-high; pulls to V+ for enable, V– for shutdown (≤170nA) |
| 10 NC | No connect | Not internally bonded; leave unconnected or tie to V– for mechanical stability |
Key Features

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 |
|---|---|---|---|
| MAX40007AUT#T | Single-channel, 800nA supply current, no shutdown, 10µV offset, 0.1µV/°C drift | Lacks dual-channel integration and shutdown - requires two devices and external enable logic for equivalent functionality | Select when lowest possible quiescent current is mandatory and dual-channel operation is not required |
| OPA391IDCKR | Dual-channel, 1.2µA supply current, 12µV offset, 0.05µV/°C drift, no EMI filter | Higher power and lower precision; lacks integrated EMI rejection - needs external RF filtering in noisy environments | Select when higher bandwidth (1.5MHz) is needed and EMI immunity is managed at board level |

FAQ
What is the maximum operating temperature specification for the LTC2067HDD#PBF?
The LTC2067HDD#PBF is fully specified over the –40°C to +125°C temperature range, as indicated by the "H" grade suffix. This includes all key parameters - input offset voltage, offset drift, input bias current, and supply current - guaranteed across the full range without derating.
Does the LTC2067HDD#PBF require external components for EMI suppression?
No, the LTC2067HDD#PBF integrates an on-chip EMI filter delivering 90dB rejection at 1.8GHz. This eliminates the need for external RC filters or ferrite beads in most RF-noisy environments, simplifying layout and reducing BOM count while maintaining signal integrity.
How does the shutdown function operate on the LTC2067HDD#PBF?
The LTC2067HDD#PBF uses an active-high SHDN pin referenced to V–. Driving SHDN ≥1.8V enables both amplifiers; pulling SHDN ≤0.8V disables them, reducing supply current to ≤170nA per amplifier. The pin must not be left floating and should be tied directly to V+ or V–.
Can the LTC2067HDD#PBF drive capacitive loads without instability?
The LTC2067HDD#PBF is stable driving ≥100pF loads in unity-gain configuration, as verified in the datasheet's small-signal overshoot plots. For loads >100pF, a series resistor (10–50Ω) between output and capacitance restores phase margin without degrading DC accuracy.
What is the purpose of the NC pin (Pin 10) on the LTC2067HDD#PBF DFN package?
Pin 10 of the LTC2067HDD#PBF is a no-connect terminal - not internally bonded. It may be left unconnected or tied to V– for mechanical reinforcement and improved thermal conduction via the PCB copper pour beneath the exposed pad.
