Product details
Overview
LT1783IS6#TRMPBF from Analog Devices (formerly Linear Technology) is a 1.25MHz, micropower, rail-to-rail input/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. It is used in battery-powered sensor conditioning and supply current sensing circuits.
For engineers reviewing the LT1783IS6#TRMPBF datasheet, LT1783IS6#TRMPBF pinout, LT1783IS6#TRMPBF application, or LT1783IS6#TRMPBF equivalent, key selection criteria include its 1.25MHz gain bandwidth, 0.42V/μs slew rate, ±4.85V output swing at ±5V supplies, –40°C to 85°C industrial temperature range, and 6-lead TSOT-23 package with SHDN functionality.
Technical Context
The LT1783IS6#TRMPBF integrates dual-input-stage architecture (NPN and PNP) enabling Over-The-Top® operation-allowing inputs to exceed V+ by up to 18V while maintaining phase reversal protection down to 9V below V–. Its internal compensation supports ≥400pF capacitive loads without oscillation.
It uses a dedicated SHDN pin (Pin 5) referenced to V–, requiring ≥2V above V– for activation; shutdown reduces supply current to 5μA and places the output in high-impedance state. Input common-mode range spans 0V to 18V on single supply and –5V to +13V on split supply, with CMRR of 68dB over full input range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT1782CS5#TRMPBF | 5-lead SOT-23, no shutdown, 200kHz GBW, 40μA IQ, same Over-The-Top® capability. | Lacks SHDN pin and lower bandwidth limits use in higher-speed current sensing or multiplexed sensor arrays. | Select when ultra-low power (<50μA) and space-constrained 5-pin layout are priorities over shutdown control. |

FAQ
What is the maximum input voltage range supported by the LT1783IS6#TRMPBF?
The LT1783IS6#TRMPBF supports an input common-mode voltage range of 0V to 18V on single supply and –5V to +13V on split supply. Critically, its Over-The-Top® architecture allows either or both inputs to operate up to 18V above V– or up to 18V above V+, independent of supply voltage-enabling direct high-side sensing without level-shifting circuitry.
Does the LT1783IS6#TRMPBF require external components for stability with capacitive loads?
The LT1783IS6#TRMPBF is internally compensated and remains stable driving ≥400pF directly. For larger capacitive loads (up to 10,000pF), a 0.22μF capacitor in series with a 150Ω resistor between OUT and ground provides effective isolation and phase margin restoration-no additional external compensation is needed for typical PCB traces or sensor cable capacitance.
How does the shutdown feature of the LT1783IS6#TRMPBF behave electrically?
When the SHDN pin (Pin 5) is driven ≥2V above V–, the LT1783IS6#TRMPBF disables its internal circuitry: supply current drops to 5μA, output enters high-impedance state (leakage <1μA between V– and V+), and input bias current falls to negligible levels. The SHDN pin draws only ≤2μA in active mode and requires no external pull-up-floating or tying to V– enables normal operation.
Can the LT1783IS6#TRMPBF be used with a 3V single supply while maintaining rail-to-rail output swing?
Yes. The LT1783IS6#TRMPBF delivers true rail-to-rail output swing on 3V supply: VOH reaches 2.91V (within 90mV of V+) and VOL sinks to 3mV above V– (0V) at no load. With 5mA load, output swing remains within 260mV of each rail-enabling full 0–3V dynamic range for ADC interfacing or low-voltage logic-level translation.
What is the guaranteed operating temperature range for the LT1783IS6#TRMPBF?
The LT1783IS6#TRMPBF is specified and tested over the industrial temperature range of –40°C to +85°C. This rating applies across all electrical parameters in the datasheet's "LT1783C/LT1783I" column, including input offset voltage (≤800μV), supply current (≤300μA), and gain bandwidth (≥1.25MHz), ensuring reliable performance in factory automation, outdoor instrumentation, and automotive cabin electronics.
