Product details
Overview
LT6000IDCB#TRPBF from Analog Devices (formerly Linear Technology) is a single-channel, precision rail-to-rail input/output operational amplifier optimized for micropower, low-voltage operation. It delivers 13 µA supply current per amplifier, 600 µV max input offset voltage, and full functionality down to 1.8 V supply - enabling use in battery-powered gas sensing front-ends and portable instrumentation where quiescent power and rail-to-rail signal swing are critical.
For engineers reviewing the LT6000IDCB#TRPBF datasheet, LT6000IDCB#TRPBF pinout, LT6000IDCB#TRPBF application, or LT6000IDCB#TRPBF equivalent, key selection criteria include guaranteed 1.8 V operation, shutdown capability (1.5 µA max), DFN-6 package footprint, and industrial temperature range (–40°C to 85°C) without performance degradation.
Technical Context
The LT6000IDCB#TRPBF employs a dual-input-stage architecture (PNP/NPN) to achieve true rail-to-rail input common-mode range (0 V to VS) while maintaining low offset and bias current across the full range. Its folded-cascode second stage and complementary drive output stage enable rail-to-rail output swing (≤30 mV from rails) with minimal load-dependent gain variation.
Shutdown control is implemented via a dedicated SHDN pin that places the amplifier in high-impedance state with ≤1.5 µA total supply current; turn-on/turn-off times are specified at 400 µs and 100 µs respectively under 10 kΩ load, supporting rapid power cycling in intermittent-sensing applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 16 V - enables direct operation from single-cell Li-ion, NiMH, or 3.3 V/5 V rails without regulation. |
| Quiescent Current | 13 µA per amplifier (typ) - extends battery life in always-on sensor nodes beyond 10 years on a CR2032 cell. |
| Input Offset Voltage | 600 µV max (–40°C to 85°C) - supports sub-mV accuracy in low-gain transducer interfaces without trimming. |
| Rail-to-Rail I/O | Input: 0 V to VS; Output: within 30 mV of VS and V– - preserves dynamic range in 1.8 V systems with no headroom loss. |
| Gain Bandwidth | 32 kHz (min) at 1.8 V - sufficient for DC–10 kHz sensor signal conditioning including active filtering. |
| Shutdown Current | 1.5 µA max total - reduces system standby power by >99% vs active mode, critical for duty-cycled oxygen sensors. |
| Operating Temp | –40°C to 85°C - qualified for industrial and outdoor portable instrumentation environments. |
Pinout & Package
LT6000IDCB#TRPBF is housed in a 6-lead, 2 mm × 3 mm plastic DFN package (DCB) with exposed pad connected to V–. The package supports high-density PCB layouts and offers θJA = 160°C/W for thermal management in compact designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SHDN) | Shutdown control input | Pulled to V+ for normal operation; driven ≤0.3 V above V– to enter shutdown (high-Z output, 1.5 µA IQ). |
| 2 (V–) | Negative supply rail | Reference for all internal circuitry; exposed pad must be soldered to PCB ground plane for thermal and electrical integrity. |
| 3 (IN–) | Inverting input | Differential input node with ±2 nA bias current (typ); requires matched source impedance to minimize offset error. |
| 4 (IN+) | Non-inverting input | Differential input node with same bias characteristics as IN–; supports common-mode range from V– to V+. |
| 5 (OUT) | Amplifier output | Capable of sourcing/sinking ≥100 µA while staying within 30 mV of either rail; high-impedance when shut down. |
| 6 (V+) | Positive supply rail | Accepts 1.8 V to 16 V; requires local 0.01 µF ceramic bypass capacitor within 1 inch for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low supply current | 13 µA per amplifier enables multi-year battery life in wireless gas sensors and handheld meters. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision micropower op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC2050CDD#TRPBF | Zero-drift architecture; 50 nV offset (max), 1.5 µA IQ, but no shutdown, DFN-8 package. | No integrated shutdown; requires external enable logic for power cycling; higher precision but less flexible in duty-cycled systems. | Select when ultra-low offset (<50 nV) dominates over shutdown capability and board area. |
| OPA333AIDBVR | Zero-drift; 10 µV offset (max), 17 µA IQ, shutdown pin, SOT-23-6 package. | Higher offset and current than LT6000IDCB#TRPBF; smaller SOT-23 footprint but lower thermal performance and no 1.8 V guarantee. | Select when SOT-23 compatibility is mandatory and 1.8 V operation is not required. |
Compared with LTC2050CDD#TRPBF and OPA333AIDBVR, the LT6000IDCB#TRPBF uniquely balances sub-µA shutdown, guaranteed 1.8 V operation, rail-to-rail I/O, and industrial temperature rating in a 2 mm × 3 mm DFN - making it optimal for space-constrained, battery-limited, wide-temperature sensor nodes where both precision and power agility are essential.

FAQ
What is the maximum input common-mode voltage range for the LT6000IDCB#TRPBF?
The LT6000IDCB#TRPBF supports a rail-to-rail input common-mode voltage range from V– to V+, meaning it operates correctly with inputs from 0 V up to the positive supply rail (e.g., 0 V to 1.8 V when powered from 1.8 V). This is verified across –40°C to 85°C and is enabled by its dual PNP/NPN input stage architecture.
Does the LT6000IDCB#TRPBF require external components for stable operation?
Yes - the LT6000IDCB#TRPBF requires a 0.01 µF ceramic capacitor placed within 1 inch of the V+ pin for supply decoupling. For heavy capacitive loads (>100 pF), a series resistor (e.g., 10–50 Ω) may be needed at the output to prevent peaking; full details are in the "Capacitive Load Handling" section of the LT6000/LT6001/LT6002 datasheet.
Can the LT6000IDCB#TRPBF drive a 10 kΩ load while maintaining rail-to-rail output swing?
Yes - the LT6000IDCB#TRPBF guarantees output swing within 30 mV of each rail with no load, and within 200 mV of each rail when sourcing or sinking 100 µA. At 10 kΩ load (100 µA at 1 V), the output remains within 200 mV of the rails, preserving >90% of full-scale range in 1.8 V systems.
What is the typical turn-on time for the LT6000IDCB#TRPBF shutdown feature?
The LT6000IDCB#TRPBF has a typical turn-on time of 400 µs when the SHDN pin transitions from low (≤0.3 V above V–) to high (V+), measured with a 10 kΩ load. This timing is consistent across –40°C to 85°C and enables predictable wake-up behavior in microcontroller-controlled sensor nodes.
Is the LT6000IDCB#TRPBF pin-compatible with other members of the LT6000/LT6001/LT6002 family?
No - the LT6000IDCB#TRPBF uses a 6-pin DFN (DCB) package, while LT6001 variants use 8-pin MSOP or 10-pin DFN, and LT6002 uses 16-pin SSOP or DFN. Pin count, pinout, and package dimensions differ; PCB layout must be specific to the LT6000IDCB#TRPBF's DCB-6 footprint.
