Product details
Overview
LTC2064IDD#PBF from Analog Devices is a dual, zero-drift, micropower operational amplifier in a 10-lead 3mm × 3mm DFN package. 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 LTC2064IDD#PBF datasheet, LTC2064IDD#PBF pinout, LTC2064IDD#PBF application, or LTC2064IDD#PBF equivalent, key selection criteria include its rail-to-rail I/O, 1.7V–5.25V supply range, integrated EMI filter (114dB rejection at 1.8GHz), and shutdown current of ≤170nA per amplifier-critical for duty-cycled battery-powered instrumentation.
Technical Context
The LTC2064IDD#PBF employs auto-zeroing and chopper stabilization to achieve near-zero DC errors while maintaining continuous-time operation across its 20kHz gain-bandwidth product. Its internal 5kHz chopping frequency is suppressed to eliminate idle tones, enabling clean DC-coupled measurement without post-processing filtering.
It features matched dual amplifiers with <100pA max input bias current over –40°C to 125°C, rail-to-rail input common-mode range (V– –0.1V to V+ +0.1V), and CMRR ≥111dB-ensuring precision in high-impedance, low-voltage sensor front-ends where thermocouple effects and leakage currents dominate error budgets.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 2µA max per amplifier - enables multi-year battery life in 10µA-average-power sensor nodes |
| Input Offset Voltage | 5µV max - supports sub-10ppm accuracy in 16-bit+ data acquisition without calibration |
| Offset Drift | 0.02µV/°C max - eliminates thermal drift-induced baseline shift in unregulated ambient environments |
| Input Bias Current | 30pA max (–40°C to 85°C) - permits use of >10MΩ feedback resistors without significant DC error |
| EMI Rejection | 114dB at 1.8GHz - suppresses cellular/WiFi interference in compact PCB layouts without external shielding |
| Shutdown Current | 170nA max per amplifier - reduces system standby power by >90% during sleep cycles |
| Gain Bandwidth | 20kHz - sufficient for slow-sensing applications including O₂, CO, and temperature transducers |
Pinout & Package
10-Lead (3mm × 3mm) Plastic DFN package with exposed pad connected to V– (Pin 4); θJA = 43°C/W, θJC = 5.5°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 9, 10 | NC / No Connect | Unbonded pins; must be left floating or grounded per layout best practices |
| 4 | V– | Negative supply rail; exposed pad internally tied to this pin-PCB connection recommended for thermal performance |
| 5 | SHDN | Active-high shutdown control referenced to V–; logic high ≥1.8V enables amplifiers, logic low ≤0.8V disables |
| 6, 7 | OUTA, OUTB | Amplifier A and B outputs; rail-to-rail swing supports full dynamic range into ADC reference buffers |
| 8 | –INA | Inverting input of Amplifier A; matched with +INA for precision differential configurations |
| 10 | +INA | Noninverting input of Amplifier A; low input capacitance (3.3pF diff) minimizes phase margin loss with capacitive sources |
Key Features
| Feature | Design Value |
|---|---|
| Zero-drift architecture | Self-calibrating circuitry eliminates 1/f noise and drift-no external nulling required for µV-level stability |
| Rail-to-rail I/O | Full input common-mode range (V– –0.1V to V+ +0.1V) and output swing within 0.15mV of rails-maximizes SNR in low-voltage systems |
| Integrated EMI filter | On-chip RC network provides 114dB rejection at 1.8GHz-eliminates need for external ferrite beads or LC filters |
| Low-charge power-up | Minimal output transient (<0.2V overshoot) during enable-prevents false triggering in downstream comparators or ADCs |
| Dual-channel crosstalk | –120dB typical at 10kHz-enables independent signal paths in compact dual-sensor interfaces without isolation components |
Applications
| Oxygen Sensor Signal Conditioning | Wireless Mesh Node Front-End |

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 | Single-channel, 900nA IS, 10µV VOS, no shutdown, SOT23-6 | Lacks dual configuration and shutdown-requires external enable logic for duty cycling | Preferred when board space is constrained and only one channel is needed |
| OPA333AIDR | Dual-channel, 17µA IS, 10µV VOS, 0.1µV/°C drift, SOIC-8 | Higher supply current and drift limit use in multi-year battery systems | Selected when higher bandwidth (350kHz) and robust SOIC handling are prioritized over micropower |

FAQ
What is the maximum operating temperature range for the LTC2064IDD#PBF?
The LTC2064IDD#PBF is specified for operation from –40°C to +85°C. This grade (denoted by "I" in the part number) is validated across that full industrial temperature range, with all key parameters-including input offset drift (0.02µV/°C max) and shutdown current (170nA max)-guaranteed under those conditions. The "H" grade variant (LTC2064HDD#PBF) extends to 125°C.
Does the LTC2064IDD#PBF require external compensation for unity-gain stability?
No, the LTC2064IDD#PBF is internally compensated and stable at unity gain (AV = +1) with capacitive loads up to 100pF. Its 20kHz gain-bandwidth product and optimized phase margin ensure robust operation in standard transimpedance and buffer configurations without added external components.
How is the exposed pad on the LTC2064IDD#PBF package connected, and is it mandatory to solder it?
The exposed pad (Pin 11) of the LTC2064IDD#PBF is internally connected to V– (Pin 4). While not strictly mandatory, Analog Devices strongly recommends soldering the pad to a V–-referenced copper plane to achieve the specified θJA = 43°C/W thermal resistance and prevent junction temperature rise during sustained output loading.
Can the LTC2064IDD#PBF drive an ADC input directly, and what is its output voltage swing capability?
Yes, the LTC2064IDD#PBF can directly drive most SAR and delta-sigma ADC inputs. Its rail-to-rail output swings to within 0.15mV of V+ and 0.1mV of V– at 499kΩ load, delivering full-scale resolution even at 1.8V supply-critical for maximizing effective number of bits (ENOB) in low-voltage data acquisition systems using the LTC2064IDD#PBF.
What is the function of the SHDN pin, and how should it be interfaced with a microcontroller GPIO?
The SHDN pin is an active-high, V–-referenced control input. To enable the LTC2064IDD#PBF, drive SHDN ≥1.8V (min logic high threshold); to disable, pull SHDN ≤0.8V (max logic low threshold). When interfacing with a 3.3V or 5V microcontroller GPIO, use a simple resistive divider or level-shifter to ensure voltage compliance-direct connection risks exceeding absolute maximum ratings if V+ < 3.3V.
