Product details
Overview
LT1783HS6#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, shutdown capability, and −40°C to +125°C operation - ideal for battery monitoring and high-side current sensing in automotive and industrial power systems.
For engineers reviewing the LT1783HS6#TRMPBF datasheet, LT1783HS6#TRMPBF pinout, LT1783HS6#TRMPBF application, or LT1783HS6#TRMPBF equivalent, key selection criteria include its guaranteed operation at 125°C junction temperature, 300μA max supply current, 850μV max input offset voltage over temperature, shutdown pin compatibility with 0.3V/2V logic thresholds, and validated performance on 3V, 5V, and ±5V supplies.
Technical Context
The LT1783HS6#TRMPBF integrates dual-input-stage architecture (NPN and PNP) enabling Over-The-Top® functionality: inputs operate 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 control is implemented via a dedicated SHDN pin (Pin 5), requiring ≥2V above V− to activate high-impedance output and reduce supply current to ≤25μA. The device maintains rail-to-rail output swing (e.g., 4.85V high / 0.8V low at 5V supply) while sourcing/sinking ≥18mA under load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 1.25MHz typical - enables stable unity-gain buffer or gain-of-10 amplification up to ~125kHz. |
| Supply Current | 300μA max at −40°C to +125°C - ensures micropower operation in always-on sensor nodes. |
| Input Offset Voltage | 850μV max over full temperature range - supports precision DC-coupled signal conditioning without trimming. |
| Input Voltage Range | 0.3V to 18V common-mode - allows direct sensing of voltages exceeding positive rail (e.g., battery voltage monitoring). |
| Output Drive | ≥18mA sink/source - drives 10kΩ loads to rail while maintaining linearity in 4–20mA transmitter interfaces. |
| Shutdown Current | ≤25μA at VSHDN = 2V - reduces system standby power in portable instrumentation. |
| Slew Rate | 0.42V/μs typical - supports 100kHz full-power sine waves at 2VP-P without distortion. |
Pinout & Package
LT1783HS6#TRMPBF is housed in a 6-lead ThinSOT™ (TSOT-23) package, 1mm profile, JEDEC MO-193 compliant, with thermal resistance θJA = 230°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Capable of rail-to-rail swing (e.g., 0.8mV above V− to 4.85V below V+ at 5V supply) and 18mA drive. |
| 2 (V−) | Negative supply rail | Reference for all internal circuitry; reverse-battery protected to −18V. |
| 3 (+IN) | Non-inverting input | Supports Over-The-Top® operation: functions with voltage up to 18V above V− or above V+. |
| 4 (V+) | Positive supply rail | Accepts 2.5V–18V total supply; bypassing with 0.1μF capacitor within 25mm is mandatory. |
| 5 (SHDN) | Shutdown control input | Active-high: ≥2V above V− disables amplifier, forces high-Z output, reduces IQ to ≤25μA. |
| 6 (−IN) | Inverting input | Phase reversal protected; handles common-mode excursions to −9V below V− without false output polarity. |
Key Features
| Feature | Design Value |
|---|---|
| Over-The-Top® Input Operation | Enables direct high-side current sensing without level-shifting, even when input exceeds V+. |
| Rail-to-Rail Input and Output | Maximizes dynamic range in single-supply systems (e.g., 3V battery-powered sensors). |
| Reverse-Battery Protection | Draws <1nA at −18V supply - eliminates need for external series diode in automotive applications. |
| Shutdown Mode | Reduces quiescent current by >90% and isolates output, enabling multiplexed sensor front-ends. |
| High-Voltage Gain | 1500V/mV minimum open-loop gain - ensures <0.1% gain error in precision closed-loop configurations. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rail-to-rail, micropower op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT1782CS6#TRMPBF | Lower GBW (200kHz), 40μA IQ, no Over-The-Top® input capability, same SOT-23-6 package. | Not suitable for inputs above V+; limited to standard rail-referenced sensing. | Select only if bandwidth <200kHz suffices and Over-The-Top® is unnecessary. |
| LT1636CS6#TRMPBF | 55μA IQ, 44V input range above V−, MSOP-8 package, no shutdown pin. | Requires PCB redesign due to different footprint; lacks integrated shutdown control. | Choose when ultra-low power dominates and layout flexibility allows MSOP-8 placement. |
Compared with LT1782CS6#TRMPBF and LT1636CS6#TRMPBF, the LT1783HS6#TRMPBF uniquely combines 125°C operation, Over-The-Top® input capability, and integrated shutdown in a 6-lead TSOT-23 - making it the only option for high-temperature, high-side sensing with power gating.

FAQ
What is the maximum junction temperature rating for the LT1783HS6#TRMPBF?
The LT1783HS6#TRMPBF has a maximum junction temperature (TJMAX) of 150°C, with guaranteed operation over the full ambient temperature range of −40°C to +125°C. This rating is validated per Absolute Maximum Ratings and confirmed in thermal characterization data showing θJA = 230°C/W for the TSOT-23-6 package.
Does the LT1783HS6#TRMPBF require external components for stability with capacitive loads?
The LT1783HS6#TRMPBF is internally compensated to drive ≥400pF capacitively without oscillation. For loads >400pF (e.g., long cables or ADC input filters), a 0.22μF capacitor in series with a 150Ω resistor between OUT and ground provides optimal compensation up to 10,000pF - as verified in the LT1783HS6#TRMPBF Typical Performance Characteristics (Figure G20).
How does the Over-The-Top® feature of the LT1783HS6#TRMPBF function in practice?
The Over-The-Top® feature allows either or both inputs of the LT1783HS6#TRMPBF to operate up to 18V above V− - independent of V+. In practice, this enables direct connection to battery terminals or high-side shunts without level shifting. For example, with V+ = 5V and V− = 0V, +IN can be held at 12V while the amplifier remains functional and linear - a capability confirmed in the LT1783HS6#TRMPBF Simplified Schematic and Applications Information section.
What is the shutdown pin threshold voltage for the LT1783HS6#TRMPBF?
The LT1783HS6#TRMPBF shutdown pin (Pin 5) has a guaranteed input low voltage (VL) of ≤0.3V and input high voltage (VH) of ≥2V relative to V−, per Electrical Characteristics tables. Activation occurs when SHDN is driven ≥2V above V−, reducing supply current to ≤25μA and placing the output in high-impedance state - behavior validated across −40°C to +125°C.
Can the LT1783HS6#TRMPBF operate from a single 3V supply?
Yes, the LT1783HS6#TRMPBF is fully specified for 3V single-supply operation (V+ = 3V, V− = 0V), with guaranteed parameters including 300μA max supply current, 850μV max input offset voltage, and rail-to-rail output swing (e.g., 0.015V to 2.85V at no load). All key specs - GBW, slew rate, and CMRR - are tested and published at 3V, confirming robust low-voltage functionality.
