Product details
Overview
LTC2066IS5#TRMPBF from Analog Devices is a single-channel, zero-drift, rail-to-rail input/output operational amplifier optimized for ultra-low-power precision sensing. It delivers 10µA maximum supply current, 5µV max input offset voltage, 0.02µV/°C max offset drift, and 35pA max input bias current over –40°C to 85°C - enabling high-resolution current sensing and sensor signal conditioning in energy-constrained wireless sensor nodes.
For engineers reviewing the LTC2066IS5#TRMPBF datasheet, LTC2066IS5#TRMPBF pinout, LTC2066IS5#TRMPBF application, or LTC2066IS5#TRMPBF equivalent, key selection criteria include shutdown current (≤170nA), EMI rejection (90dB at 1.8GHz), and compatibility with 1.7V–5.25V supplies in TSOT-23 packaging for space- and power-sensitive designs.
Technical Context
The LTC2066IS5#TRMPBF employs auto-zeroing and chopper-stabilized architecture with 25kHz internal chopping frequency to eliminate 1/f noise and minimize DC errors. Its integrated EMI filter suppresses RF interference without external components, and its low-charge power-up circuit reduces transient error during duty-cycled operation.
It features rail-to-rail input common-mode range (V– –0.1V to V+ +0.1V) and output swing (within 0.15mV of rails at light load), supporting direct interfacing with low-voltage ADCs and microcontrollers. The SHDN pin operates with logic thresholds referenced to V– (VH ≥ 1.0V, VL ≤ 0.65V), enabling clean enable/disable control in battery-powered systems.
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 - supports µV-level DC measurement accuracy without calibration. |
| Offset Drift | ±0.02µV/°C max - ensures stable baseline over industrial temperature range (–40°C to 85°C). |
| Input Bias Current | 35pA max (–40°C to 85°C) - permits use of MΩ-range feedback resistors without significant error. |
| EMI Rejection | 90dB at 1.8GHz - eliminates need for external RF filtering in noisy environments (e.g., cellular/Wi-Fi co-location). |
| Shutdown Current | 170nA max per amplifier - reduces system standby power by >98% vs active mode. |
| Gain Bandwidth | 100kHz - sufficient for DC–10kHz sensor signals (e.g., thermistor, gas sensor outputs). |
Pinout & Package
Package: 5-lead TSOT-23 (3.0mm × 1.7mm × 0.9mm), RoHS-compliant, moisture-sensitive level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 OUT | Amplifier output | Rail-to-rail capable; drives 499kΩ load to within 0.15mV of V+ and 0.1mV of V–. |
| 2 V– | Negative supply | Reference for SHDN threshold and input common-mode range; requires local bypass capacitor. |
| 3 +IN | Noninverting input | High-impedance MOSFET input; sensitive to thermocouple effects - matched layout critical. |
| 4 –IN | Inverting input | Same topology as +IN; differential pair inputs require symmetrical PCB routing and thermal environment. |

FAQ
What is the maximum operating temperature range for the LTC2066IS5#TRMPBF?
The LTC2066IS5#TRMPBF is specified for operation from –40°C to +85°C. This industrial-grade temperature range is confirmed in the Absolute Maximum Ratings table and Electrical Characteristics section of the official datasheet, with all key parameters (e.g., offset drift, supply current) guaranteed across this span.
Does the LTC2066IS5#TRMPBF support rail-to-rail input and output operation?
Yes, the LTC2066IS5#TRMPBF supports rail-to-rail input (V– –0.1V to V+ +0.1V) and rail-to-rail output (within 0.15mV of V+ and 0.1mV of V– at RL = 499kΩ). This capability is explicitly verified in the Electrical Characteristics table under VCMR and VOL/VOH parameters.
How does the SHDN pin function on the LTC2066IS5#TRMPBF?
The SHDN pin on the LTC2066IS5#TRMPBF is referenced to V–: driving it to V+ enables the amplifier, while tying it to V– disables it and reduces supply current to ≤170nA. Logic thresholds are VH ≥ 1.0V and VL ≤ 0.65V (referred to V–), as documented in the Electrical Characteristics table.
What is the EMI rejection performance of the LTC2066IS5#TRMPBF?
The LTC2066IS5#TRMPBF provides 90dB EMI rejection at 1.8GHz, measured as EMIRR = 20·log(VRF/ΔVOS). This value is specified in the Electrical Characteristics table and results from an integrated on-chip EMI filter - eliminating need for external ferrite beads or RC networks.
Can the LTC2066IS5#TRMPBF be used with a 1.7V supply?
Yes, the LTC2066IS5#TRMPBF operates from 1.7V to 5.25V, with all key specifications (including supply current, offset voltage, and PSRR) guaranteed across this full range. The minimum 1.7V supply is explicitly stated in the Absolute Maximum Ratings and Electrical Characteristics sections.
