Product details
Overview
LT1783CS6#TRMPBF from Analog Devices (formerly Linear Technology) is a 1.25MHz, micropower, rail-to-rail input and output operational amplifier in a 6-lead TSOT-23 package, operating from 2.5V to 18V total supply. It features Over-The-Top® operation (inputs up to 18V above V– or above V+), reverse-battery protection to 18V, and shutdown capability reducing quiescent current to 5μA - ideal for battery-powered current sensing and supply monitoring.
For engineers reviewing the LT1783CS6#TRMPBF datasheet, LT1783CS6#TRMPBF pinout, LT1783CS6#TRMPBF application, or LT1783CS6#TRMPBF equivalent, key selection criteria include its 18V input common-mode range beyond rails, 300μA max supply current at 0°C–70°C, 18mA output drive, shutdown-controlled high-impedance output, and guaranteed performance over commercial temperature range.
Technical Context
The LT1783CS6#TRMPBF integrates dual-input-stage architecture (NPN and PNP) enabling Over-The-Top® operation: inputs function correctly when ≥18V above V– or >V+, with phase reversal protection for inputs down to 9V below V–. Its internal compensation supports ≥400pF capacitive loads without oscillation.
Shutdown is controlled via SHDN pin (Pin 5), requiring ≥2V above V– to disable; during shutdown, output enters high-impedance state and supply current drops to ≤18μA. The device is specified for single-supply (0V–18V input range) and split-supply (±1.35V min) operation, with PSRR ≥90dB and CMRR ≥68dB across full common-mode range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 1.25MHz - enables stable unity-gain buffer or gain-of-10 amplification up to ~125kHz. |
| Slew Rate | 0.42V/μs - supports 2V output step settling within 12μs to 0.1% (at AV = –1, VS = 5V). |
| Supply Current | 300μA max (0°C–70°C) - enables multi-year battery life in always-on sensor nodes. |
| Input Offset Voltage | 800μV max - ensures ≤0.8mV error in precision current-sense applications at room temperature. |
| Output Drive | 18mA min - drives 200Ω loads while maintaining rail-to-rail swing (e.g., 4–20mA transmitter output stage). |
| Common-Mode Range | 0V to 18V (single supply) - allows direct sensing of voltages above V+ in high-side current monitoring. |
| Shutdown Current | 5μA typ - reduces system standby power by >98% vs active mode. |
Pinout & Package
LT1783CS6#TRMPBF is housed in a 6-lead ThinSOT™ (TSOT-23) package, 1.00mm max height, JEDEC MO-193 compliant, with 0.95mm pitch and 2.80mm × 2.90mm footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier Output | Full rail-to-rail swing (≤60mV from rails); high-impedance when SHDN asserted. |
| 2 (V–) | Negative Supply / Ground Reference | Return path for supply and signal; input common-mode extends 10V below this pin. |
| 3 (+IN) | Non-Inverting Input | Accepts signals up to 18V above V– or >V+; protected by series 1kΩ resistor and clamp diode. |
| 4 (V+) | Positive Supply | Supports 2.5V–18V total supply; requires local 0.1μF bypass capacitor. |
| 5 (SHDN) | Shutdown Control Input | Active-high: ≥2V above V– disables amplifier; leakage <1μA in shutdown. |
| 6 (–IN) | Inverting Input | Same Over-The-Top® and phase-reversal protection as +IN; differential voltage limit = 18V. |
Key Features
| Feature | Design Value |
|---|---|
| Over-The-Top® Input Operation | Enables high-side current sensing without level-shifting: inputs functional at V+ + 18V or V– + 18V. |
| Rail-to-Rail Input & Output | Supports full dynamic range utilization in low-voltage (3V) systems: input 0V–18V, output 0V–(V+–0.06V). |
| Reverse-Battery Protection | Draws <1nA at –18V supply - eliminates need for external series diode in automotive/battery systems. |
| Shutdown Mode | Reduces supply current to 5μA and isolates output - essential for intermittent measurement architectures. |
| Phase Reversal Protection | Prevents false outputs when inputs drop to –9V relative to V– - critical for fault-tolerant industrial interfaces. |
Applications
| High-Side Current Sensing | Battery Monitoring System |
|---|---|
Use Scenario: Measuring charge/discharge current in Li-ion battery packs using a high-side shunt resistor. IC Role / Device Role / Timing Role: Precision current-to-voltage converter with input referenced to battery positive terminal.

Equivalent & Alternatives
The following parts are listed as comparable options for similar op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT1783IS6#TRMPBF | Wider operating temperature range (–40°C to 85°C) vs. LT1783CS6#TRMPBF (0°C to 70°C); otherwise identical electrical specs and pinout. | Suitable for industrial environments with extended thermal cycling; not required for consumer-grade portable instrumentation. | Select LT1783IS6#TRMPBF when ambient temperature may fall below 0°C or exceed 70°C during operation. |
| LT1782CS5#TRMPBF | 5-lead SOT-23 (no shutdown), 200kHz GBW, 40μA supply current - lower power but no SHDN pin or Over-The-Top® headroom. | Limited to low-bandwidth, ultra-low-power applications where input voltage stays within rail limits (e.g., sensor biasing). | Choose LT1782CS5#TRMPBF only if shutdown and >V+ input capability are unnecessary and 200kHz bandwidth suffices. |
Compared with LT1783IS6#TRMPBF, the LT1783CS6#TRMPBF trades extended temperature qualification for lower cost in commercial-grade designs; versus LT1782CS5#TRMPBF, it provides critical Over-The-Top® functionality and shutdown at higher power and speed - making it indispensable for high-side sensing and intermittent operation.

FAQ
What is the maximum input voltage range supported by the LT1783CS6#TRMPBF?
The LT1783CS6#TRMPBF supports an input common-mode voltage range of 0V to 18V on single supply, and extends 18V above V– regardless of V+. Its inputs tolerate differential voltages up to 18V and common-mode excursions to +24V or –10V relative to V–, enabling direct high-side sensing without external level shifters. This Over-The-Top® capability is confirmed in the Absolute Maximum Ratings and Applications Information sections of the datasheet.
Does the LT1783CS6#TRMPBF require external compensation for capacitive loads?
No, the LT1783CS6#TRMPBF is internally compensated to drive ≥400pF capacitively without instability. For larger loads up to 10,000pF, a 0.22μF capacitor in series with a 150Ω resistor between output and ground provides stable operation across all output currents - a design detail verified in the Applications Information section and Typical Performance Characteristics (G19–G20).
How does the shutdown feature affect output behavior in the LT1783CS6#TRMPBF?
When the SHDN pin (Pin 5) is driven ≥2V above V–, the LT1783CS6#TRMPBF disables its amplifier core, reducing supply current to ≤18μA and placing the OUT pin (Pin 1) in high-impedance state with leakage <1μA. This isolation prevents loading of downstream circuitry - a critical feature validated in Electrical Characteristics (ISHDN, Shutdown Output Leakage Current) and confirmed in the Simplified Schematic and Shutdown application notes.
What is the guaranteed operating temperature range for the LT1783CS6#TRMPBF?
The LT1783CS6#TRMPBF is guaranteed to operate from 0°C to 70°C (commercial grade). While characterized from –40°C to 85°C, only the 0°C–70°C range is fully tested and QA sampled per datasheet Note 4. This specification is explicitly stated in the Order Information table and Absolute Maximum Ratings section.
Can the LT1783CS6#TRMPBF be used with split supplies such as ±5V?
Yes, the LT1783CS6#TRMPBF operates on split supplies with minimum ±1.35V (2.7V total), supporting ±5V configurations. Its input common-mode range extends from –5V to +13V under ±5V supply, and PSRR remains ≥90dB. These parameters are measured and specified in the Electrical Characteristics tables for ±5V conditions, confirming robust performance in bipolar signal chains.
