Product details
Overview
LTC2066IS5#TRPBF 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#TRPBF datasheet, LTC2066IS5#TRPBF pinout, LTC2066IS5#TRPBF application, or LTC2066IS5#TRPBF equivalent, key selection criteria include micropower shutdown (170nA), integrated EMI filtering (90dB at 1.8GHz), low-charge power-up behavior, and TSOT-23-5 package compatibility with space-constrained PCB layouts.
Technical Context
The LTC2066IS5#TRPBF employs auto-zeroing and chopper-stabilized architecture to achieve near-zero DC errors while maintaining continuous-time operation across its 100kHz gain-bandwidth product. Its internal 25kHz chopping frequency is suppressed to minimize clock feedthrough artifacts in sensitive measurement paths.
It features a dedicated SHDN pin referenced to V–, enabling logic-controlled sleep mode with sub-200nA quiescent current. The amplifier supports rail-to-rail operation from 1.7V to 5.25V supply, with output swing within 0.15mV of rails under light load - critical for maximizing dynamic range in low-voltage systems.

Pinout & Package
The LTC2066IS5#TRPBF is housed in a 5-lead plastic TSOT-23 package (θJA = 215°C/W), with exposed pad connected internally to V– for thermal and noise performance optimization.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 V– | Negative supply | Reference for SHDN threshold and output swing; connects to exposed pad |
| 3 +IN | Noninverting input | High-impedance MOSFET node; matched layout critical to minimize thermocouple EMF |
| 4 –IN | Inverting input | Accepts feedback network; sensitive to clock feedthrough from high-Z sources |
| 5 V+ | Positive supply | 1.7V–5.25V operation; bypass capacitor mandatory for EMI immunity |
Key Features

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 | Higher 15µA supply current; no shutdown mode; 10µV offset | Lacks micropower sleep capability - unsuitable for duty-cycled sensor nodes | Select when shutdown functionality is unnecessary and higher bandwidth (200kHz) is required |
| AD8500ARJZ-R7 | Lower 1.2µA supply current but 20µV offset and 0.3µV/°C drift | Drift dominates error budget above 25°C - limits use in wide-temperature industrial settings | Select only for cost-sensitive, room-temperature applications where 10x lower IQ is critical |
Compared with MAX40007AUT+T and AD8500ARJZ-R7, the LTC2066IS5#TRPBF uniquely balances sub-10µA IQ, <5µV offset, and 0.02µV/°C drift - making it the only option qualified for battery-powered, high-accuracy, wide-temperature sensing without calibration overhead.

FAQ
What is the maximum operating temperature range for the LTC2066IS5#TRPBF?
The LTC2066IS5#TRPBF 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 Analog Devices datasheet Rev. B, where all "l"-marked parameters apply across this full range.
Does the LTC2066IS5#TRPBF require external capacitors for stability?
Yes, the LTC2066IS5#TRPBF requires a minimum 100nF ceramic bypass capacitor between V+ and V– pins, placed as close as possible to the device. This is explicitly mandated in the PIN FUNCTIONS section for EMI filtering and power supply decoupling, and omission risks degraded PSRR and increased susceptibility to RF interference.
Can the LTC2066IS5#TRPBF drive capacitive loads directly?
The LTC2066IS5#TRPBF can drive up to 100pF capacitive loads without external compensation, as verified by Small Signal Overshoot vs Load Capacitance plots (Figures 2066 G58/G59). Driving >100pF requires isolation resistor or gain adjustment per Application Information guidelines to maintain phase margin.
What is the function of the SHDN pin on the LTC2066IS5#TRPBF?
The SHDN pin on the LTC2066IS5#TRPBF is a V–-referenced enable control: tying it to V+ activates the amplifier, while connecting it to V– places it in shutdown mode drawing ≤170nA. Its logic thresholds (VH = 1.8V, VL = 0.8V) allow direct interfacing with 1.8V microcontroller GPIOs without level-shifting circuitry.
How does the LTC2066IS5#TRPBF handle EMI compared to standard op-amps?
The LTC2066IS5#TRPBF integrates an on-die EMI filter delivering 90dB rejection at 1.8GHz - a feature documented in the ELECTRICAL CHARACTERISTICS table under EMIRR. This eliminates the need for external ferrite beads or RC filters commonly required with conventional op-amps in cellular/WiFi-rich environments.
