Product details
Overview
LT6004CDD#TRPBF from Analog Devices (formerly Linear Technology) is a dual rail-to-rail input/output precision operational amplifier optimized for micropower battery-powered systems. It operates from 1.6V to 16V supply, draws ≤1.6µA per amplifier at 5V, features 500µV max input offset voltage, 90pA max input bias current, and drives 500pF capacitive loads - enabling high-accuracy signal conditioning in portable gas monitors and solar-powered sensor nodes.
For engineers reviewing the LT6004CDD#TRPBF datasheet, LT6004CDD#TRPBF pinout, LT6004CDD#TRPBF application, or LT6004CDD#TRPBF equivalent, this page delivers verified electrical specs, package mapping to the 8-lead 3mm × 3mm DFN, thermal performance data up to 85°C, and real-world design guidance for low-voltage, ultra-low-quiescent-current analog front-ends.
Technical Context
The LT6004CDD#TRPBF employs a complementary PNP/NPN input stage with automatic crossover near V+ – 0.9V, enabling true rail-to-rail common-mode input range (0V to V+) while maintaining <500µV offset across the full range. Its folded-cascode second stage and complementary drive output stage deliver rail-to-rail output swing (≤100mV from rails, no load) without phase reversal, even when inputs are driven 9V below V–.
Internal cancellation circuitry holds input bias current ≤90pA over 0.3V to V+ – 0.3V common-mode range; beyond that, IB rises into the nA range. The 100,000 min open-loop gain (AVOL) is specified driving 20kΩ loads, and stability is maintained up to 500pF capacitive loading without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.6V to 16V - enables direct operation from single-cell Li-ion (3.0–4.2V), alkaline (1.5V), or 12V industrial rails without regulation. |
| Quiescent Current | 1.6µA per amplifier max at 5V - supports >10-year battery life in always-on sensor nodes drawing <1µA system average current. |
| Input Offset Voltage | 500µV max (0°C to 70°C) - ensures ≤0.5mV error in 10-bit ADC interfaces with 5V full-scale range. |
| Input Bias Current | 90pA max - allows use with >100MΩ source impedances (e.g., pH electrodes, piezoresistive sensors) without significant offset drift. |
| Capacitive Load Drive | 500pF - eliminates need for isolation resistors when driving ADC input caps or long PCB traces in data acquisition systems. |
| CMRR / PSRR | 100dB / 95dB - rejects power supply ripple and common-mode noise in noisy industrial environments (e.g., motor drives, PLC I/O). |
| Operating Temp Range | –40°C to 85°C - qualified for commercial/industrial ambient conditions in outdoor sensor enclosures and handheld instruments. |
Pinout & Package
LT6004CDD#TRPBF is housed in an 8-lead 3mm × 3mm plastic DFN package with exposed pad connected to V–. Thermal resistance θJA = 160°C/W with minimal PCB copper; soldering the exposed pad reduces junction-to-board thermal resistance significantly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: OUT A | Amplifier A output | Rail-to-rail swing (≤100mV from V+, ≤50mV from V–); capable of sourcing/sinking ≥1mA at 5V. |
| 2: –IN A | Inverting input A | Differential pair node; protected by 600kΩ series resistors against overvoltage beyond rails. |
| 3: +IN A | Non-inverting input A | Differential pair node; matched impedance critical for minimizing IB-induced offset errors. |
| 4: V– | Negative supply | Reference for both amplifiers; exposed pad must be soldered to PCB ground plane for thermal and electrical integrity. |
| 5: V+ | Positive supply | Bypass with 0.01µF ceramic capacitor within 1 inch; add 4.7µF electrolytic for heavy transient loads. |
| 6: OUT B | Amplifier B output | Independent rail-to-rail output; electrically isolated from OUT A except via shared V+/V– supplies. |
| 7: –IN B | Inverting input B | Matches Pin 2 characteristics; supports dual-channel instrumentation (e.g., differential sensor + reference buffer). |
| 8: +IN B | Non-inverting input B | Matches Pin 3 characteristics; enables synchronous dual-signal processing without cross-talk. |
Key Features
| Feature | Design Value |
|---|---|
| Ultralow quiescent current | 1.6µA per amplifier max ensures sub-µA system sleep modes remain viable in energy-harvesting designs. |
| Rail-to-rail input & output | 0V to V+ input range and ≤100mV from rails output swing maximize dynamic range in 1.8V–3.3V microcontroller systems. |
| Phase reversal protection | Prevents output polarity inversion when inputs are driven up to 9V below V–, eliminating latch-up risk in fault-tolerant sensor interfaces. |
| Guaranteed 500pF capacitive drive | Enables direct connection to SAR ADC input capacitors (e.g., AD7980, ADS8860) without stability-compromising series resistors. |
| Low input offset drift | 2µV/°C typical drift maintains calibration integrity across –40°C to 85°C ambient without software compensation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2333AIDR | Zero-drift architecture; 0.02µV/°C offset drift vs. 2µV/°C; 17µA IQ vs. 1.6µA; 360kHz GBW vs. 2kHz. | Higher precision required in DC-coupled medical diagnostics; less suitable for multi-year battery life targets. | Select OPA2333AIDR only when offset drift dominates error budget and supply current >10× higher is acceptable. |
| MCP6V81-E/SN | Zero-drift; 0.25µV/°C drift; 600nA IQ; 1MHz GBW; 5-pin SC70 package (single only). | Better AC performance for sensor signal chains needing >10kHz bandwidth; not pin-compatible with LT6004CDD#TRPBF's dual DFN. | Choose MCP6V81-E/SN for single-channel, higher-speed, zero-drift needs; avoid for dual-channel space-constrained layouts. |
Compared with OPA2333AIDR and MCP6V81-E/SN, the LT6004CDD#TRPBF uniquely balances sub-2µA quiescent current, dual-channel integration in 3mm × 3mm DFN, and guaranteed 500pF drive - making it optimal for ultra-long-life, space-limited, low-bandwidth precision sensing where zero-drift isn't mandatory.

FAQ
What is the maximum capacitive load the LT6004CDD#TRPBF can drive without external compensation?
The LT6004CDD#TRPBF is fully characterized and guaranteed to remain stable driving up to 500pF capacitive loads across all supply voltages (1.6V to 16V) and temperatures (–40°C to 85°C). This specification eliminates the need for isolation resistors when interfacing with ADC input capacitors or long PCB traces, simplifying layout and preserving signal integrity in data acquisition systems using the LT6004CDD#TRPBF.
Does the LT6004CDD#TRPBF support true rail-to-rail input operation down to the negative supply rail?
Yes, the LT6004CDD#TRPBF supports true rail-to-rail input operation from V– to V+. Its dual-input-stage architecture (PNP and NPN differential pairs) ensures continuous functionality across the entire common-mode range. Input offset voltage remains ≤500µV max over 0V to V+ (at 0°C to 70°C), and phase reversal is prevented even when inputs are driven up to 9V below V– - a key reliability feature confirmed in the LT6004CDD#TRPBF datasheet.
What is the guaranteed operating temperature range for the LT6004CDD#TRPBF?
LT6004CDD#TRPBF is specified for commercial temperature operation from 0°C to 70°C and guaranteed functional from –40°C to 85°C. Electrical parameters including input offset voltage (500µV max), supply current (1.6µA max), and CMRR (100dB) are tested and warranted over the 0°C to 70°C range, while extended functionality across –40°C to 85°C is assured per Analog Devices' qualification standards for the LT6004CDD#TRPBF.
Can the LT6004CDD#TRPBF be used with a single 1.8V supply?
Yes, the LT6004CDD#TRPBF is fully specified and guaranteed to operate on a single 1.8V supply. At 1.8V, it delivers ≤1.4µA per amplifier quiescent current, 500µV max input offset voltage, and rail-to-rail input/output swing - enabling precision analog signal conditioning in modern ultra-low-voltage microcontroller systems. Minimum supply voltage is 1.6V, verified by PSRR testing per the LT6004CDD#TRPBF datasheet.
Is the exposed pad on the LT6004CDD#TRPBF's DFN package electrically connected, and how should it be handled?
Yes, the exposed pad on the LT6004CDD#TRPBF's 8-lead 3mm × 3mm DFN package is internally connected to V– and must be soldered to the PCB ground plane. This connection is mandatory for thermal management (θJA = 160°C/W assumes exposed pad soldering) and electrical stability. Failure to solder the pad may cause thermal runaway under sustained load or increased noise susceptibility - a requirement explicitly stated in the LT6004CDD#TRPBF package documentation.
