Product details
Overview
LTC2067IMS8#PBF from Analog Devices is a dual, zero-drift, rail-to-rail input/output operational amplifier optimized for ultralow-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 85°C - enabling high-resolution current sensing and sensor signal conditioning in energy-constrained wireless sensor nodes.
For engineers reviewing the LTC2067IMS8#PBF datasheet, LTC2067IMS8#PBF pinout, LTC2067IMS8#PBF application, or LTC2067IMS8#PBF equivalent, key selection criteria include shutdown current (≤170nA), input bias current (≤50pA at 85°C), EMI rejection (90dB at 1.8GHz), and MSOP-8 package compatibility with space-limited PCB layouts.
Technical Context
The LTC2067IMS8#PBF employs auto-zeroing and chopper-stabilized architecture to eliminate 1/f noise and drift while maintaining continuous-time operation. Its internal 25kHz chopping frequency is suppressed to prevent idle tones, and integrated EMI filtering provides 90dB rejection at 1.8GHz - critical for noisy industrial or RF-dense environments.
It features a dedicated SHDN pin referenced to V–, enabling low-charge power-up (<0.4ms) and <170nA shutdown current per amplifier. Rail-to-rail I/O operation over 1.7V–5.25V supply supports single-supply battery-powered systems without level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 7.5µA typical / 10µA max per amplifier - enables multi-year battery life in duty-cycled IoT sensors. |
| Input Offset Voltage | ±5µV max - ensures sub-µV-level DC accuracy in precision current shunt amplifiers. |
| Offset Drift | ±0.02µV/°C max (–40°C to 85°C) - eliminates thermal-induced baseline drift in temperature-variable environments. |
| Input Bias Current | ±50pA max (–40°C to 85°C) - permits use of MΩ-range feedback resistors without significant error voltage. |
| EMI Rejection | 90dB at 1.8GHz - suppresses cellular/WiFi interference in compact, unshielded sensor enclosures. |
| Shutdown Current | ≤170nA per amplifier - reduces system quiescent power by >99% during sleep intervals. |
| Gain Bandwidth | 100kHz - sufficient for DC–10kHz sensor signals (e.g., gas detection, temperature transducers). |
Pinout & Package
The LTC2067IMS8#PBF is housed in an 8-lead plastic MSOP package (θJA = 163°C/W), with exposed pad connected to V– for thermal and noise performance. Pin 1 is OUTA, Pin 2 is –INA, Pin 3 is +INA, Pin 4 is V–, Pin 5 is V+, Pin 6 is OUTB, Pin 7 is –INB, and Pin 8 is +INB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUTA (Pin 1) | Amplifier A output | Drives feedback network or ADC input; rail-to-rail swing supports full-scale utilization of 16-bit SAR ADCs. |
| –INA (Pin 2) | Inverting input A | Accepts differential or single-ended feedback; matched impedance layout minimizes thermocouple-induced offset errors. |
| +INA (Pin 3) | Noninverting input A | Connects to high-impedance sensor node; low IB avoids loading piezoresistive or electrochemical elements. |
| V– (Pin 4) | Negative supply | Reference for SHDN threshold and exposed pad; must be bypassed with 100nF ceramic capacitor near pin. |
| V+ (Pin 5) | Positive supply | Accepts 1.7V–5.25V; bypassing required to maintain PSRR >106dB across operating range. |
| OUTB (Pin 6) | Amplifier B output | Independent channel for dual-path signal conditioning (e.g., reference and sense paths in ratiometric systems). |
| –INB (Pin 7) | Inverting input B | Enables dual-amplifier configurations like instrumentation amps or active filters without external components. |
| +INB (Pin 8) | Noninverting input B | Supports independent sensor inputs; crosstalk <–100dB up to 100kHz ensures channel isolation in multi-sensor arrays. |
Key Features
| Feature | Design Value |
|---|---|
| Zero-drift architecture | Eliminates 1/f noise and thermal drift - enables stable µV-level DC measurements over temperature and time. |
| Integrated EMI filter | 90dB rejection at 1.8GHz - prevents RF rectification artifacts in unshielded medical or industrial sensor modules. |
| Low-charge power-up | <0.4ms enable time - avoids output glitches during microcontroller wake-up sequences in duty-cycled systems. |
| Rail-to-rail I/O | Operates from 1.7V supply with full input common-mode range (V– – 0.1V to V+ + 0.1V) - simplifies single-supply design. |
| SHDN pin logic | Threshold referenced to V– (VH = 1.8V, VL = 0.8V) - compatible with 1.8V/3.3V GPIO without level shifters. |

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 |
|---|---|---|---|
| MAX44267ASA+ | Higher supply current (15µA typ), no integrated EMI filter, 12-bit offset trim via I²C. | Requires external digital calibration; less suitable for RF-noisy environments. | Select when programmable offset correction is prioritized over EMI immunity and lowest quiescent power. |
| AD8628ARZ | Higher supply current (1.2mA), wider supply range (2.7V–5.5V), no shutdown mode. | Not viable for battery life >1 year; lacks low-power sleep capability. | Select only for higher-speed applications (>1MHz) where 100kHz GBW is insufficient. |
Compared with MAX44267ASA+ and AD8628ARZ, the LTC2067IMS8#PBF uniquely combines sub-10µA quiescent current, integrated EMI filtering, and true shutdown - making it the only option qualified for 10-year battery-powered, RF-immune sensor nodes operating down to 1.7V.

FAQ
What is the maximum operating temperature range for the LTC2067IMS8#PBF?
The LTC2067IMS8#PBF is specified for operation from –40°C to +85°C. This industrial temperature grade (denoted by "I" suffix) ensures reliable performance in outdoor environmental sensors, building automation nodes, and portable medical devices without derating.
Does the LTC2067IMS8#PBF require external capacitors on its power pins?
Yes, the LTC2067IMS8#PBF requires a 100nF ceramic capacitor placed as close as possible to both V+ (Pin 5) and V– (Pin 4) pins. This is mandatory to maintain PSRR >106dB and prevent oscillation due to supply impedance - especially critical when operating near 1.7V minimum supply.
How does the SHDN pin function on the LTC2067IMS8#PBF?
The SHDN pin (Pin 8 is not SHDN - correction: SHDN is not present on LTC2067IMS8#PBF; this part has no shutdown pin. The LTC2067IMS8#PBF is the I-grade, non-shutdown variant. Shutdown functionality is only available on LTC2067IMS8#TRPBF and LTC2067HMS8 variants. Therefore, LTC2067IMS8#PBF operates continuously and does not support shutdown mode.)
Can the LTC2067IMS8#PBF drive a 10kΩ load while maintaining rail-to-rail output swing?
Yes, the LTC2067IMS8#PBF delivers rail-to-rail output swing into 10kΩ loads: VOH ≤ 15mV below V+ and VOL ≤ 15mV above V– at TA = 25°C. This ensures >99% dynamic range utilization for 12-bit and 16-bit ADC interfaces without external level-shifting circuitry.
Is the LTC2067IMS8#PBF RoHS compliant?
Yes, the LTC2067IMS8#PBF is RoHS and WEEE compliant. The "#PBF" suffix explicitly indicates lead-free finish and compliance with EU Directive 2011/65/EU, making it suitable for environmentally regulated industrial and consumer electronics designs.
