Product details
Overview
LTC2064HDD#PBF from Analog Devices is a dual-channel, zero-drift, micropower operational amplifier in a 10-lead (3mm × 3mm) DFN package, rated for –40°C to 125°C operation. It delivers 2µA maximum supply current per amplifier, 5µV max input offset voltage, and 0.02µV/°C max offset drift-enabling high-resolution sensor signal conditioning in ultra-low-power systems such as wireless gas sensors and energy-harvesting nodes.
For engineers reviewing the LTC2064HDD#PBF datasheet, LTC2064HDD#PBF pinout, LTC2064HDD#PBF application, or LTC2064HDD#PBF equivalent, key selection criteria include its rail-to-rail I/O, integrated EMI filter (114dB rejection at 1.8GHz), shutdown current ≤170nA, and guaranteed performance across automotive-grade temperature range.
Technical Context
The LTC2064HDD#PBF employs auto-zeroing and chopper-stabilized architecture to achieve near-zero DC errors while maintaining continuous-time operation. Its internal 5kHz chopping frequency is suppressed to eliminate idle tones, and the integrated EMI filter rejects RF interference up to 2.4GHz without external components.
Each amplifier features independent shutdown control via SHDN pin (logic-high threshold ≥1.8V referenced to V–), low-charge power-up (<2ms turn-on time), and rail-to-rail input/output swing across 1.7V to 5.25V supply. Input bias current remains ≤100pA over –40°C to 125°C, enabling use with multi-MΩ feedback networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 2µA max per amplifier - enables multi-year battery life in duty-cycled sensor nodes. |
| Input Offset Voltage | 5µV max - supports sub-µV-level precision in oxygen or CO₂ sensing front-ends. |
| Offset Drift | 0.02µV/°C max - ensures stable calibration over automotive temperature range without recalibration. |
| Input Bias Current | 100pA max (–40°C to 125°C) - allows 10MΩ+ feedback resistors without significant DC error. |
| EMI Rejection | 114dB at 1.8GHz - eliminates need for external RF filtering in noisy industrial or automotive environments. |
| Shutdown Current | 170nA max per amplifier - reduces system standby power by >90% vs active mode. |
| Gain Bandwidth | 20kHz - sufficient for DC-coupled thermocouple, RTD, or electrochemical sensor amplification. |
Pinout & Package

| Integrated EMI filter | 114dB rejection at 1.8GHz - suppresses cellular/WiFi interference without external LC filters or ferrites. |
| Low-charge power-up | <2ms enable time with minimal output transient - prevents false triggers in wake-on-event sensor systems. |
| Self-calibrating architecture | Eliminates 1/f noise and drift without introducing chopping artifacts - enables true DC accuracy in static measurements. |
| High PSRR/CMRR | 126dB PSRR and 130dB CMRR - rejects supply ripple and common-mode noise in battery-powered instrumentation. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX40007AUT#T | Single-channel, 900nA supply current, 10µV offset, no shutdown, SOT23-6 | Lacks dual-channel integration and shutdown; lower power but higher offset and no EMI filter | Preferred only when single-channel function and absolute minimum quiescent current outweigh need for dual amplifiers and RF immunity |

FAQ
What is the maximum operating temperature range for the LTC2064HDD#PBF?
The LTC2064HDD#PBF is fully specified from –40°C to +125°C, meeting automotive-grade thermal requirements. This extended range is confirmed in the Absolute Maximum Ratings table and Electrical Characteristics sections of the official Analog Devices datasheet Rev. C, where all "H" grade parameters-including input offset drift and shutdown current-are guaranteed across this full span.
Does the LTC2064HDD#PBF require external EMI filtering components?
No. The LTC2064HDD#PBF integrates an on-die EMI filter delivering 114dB rejection at 1.8GHz, as measured per the EMIRR test condition in the datasheet. This eliminates the need for external RC filters, ferrite beads, or shielding in applications exposed to cellular, WiFi, or Bluetooth RF fields-verified in typical performance plots Figure 21 and Applications Information section.
How does the shutdown functionality work on the LTC2064HDD#PBF?
The LTC2064HDD#PBF uses a single SHDN pin (Pin 5) to control both amplifiers. When pulled to V– (0V), supply current drops to ≤170nA per amplifier. Logic-high threshold is ≥1.8V (referred to V–), and the pin draws ≤–150nA when held at 0V. This behavior is documented in the Electrical Characteristics table under VH, VL, and ISHDN parameters.
Can the LTC2064HDD#PBF drive a 10kΩ load rail-to-rail?
Yes. The LTC2064HDD#PBF guarantees rail-to-rail output swing into 10kΩ loads: VOH ≤7mV below V+ and VOL ≤5.5mV above V– at TA = 25°C, per the Electrical Characteristics table. Performance is maintained across –40°C to 125°C, with worst-case swing degradation bounded in the "Output Voltage Swing Low/High" rows.
Is the exposed pad on the LTC2064HDD#PBF package required to be connected?
Yes. The exposed pad (Pin 11) is internally connected to V– (Pin 4) and must be soldered to a PCB copper pour tied to the V– net. This connection is mandatory for thermal performance (θJA = 43°C/W) and electrical stability, as stated in the Pin Configuration diagram and Absolute Maximum Ratings note regarding thermal resistance dependency on board metal area.
