Product details
Overview
LT1809IS6#TRMPBF from Analog Devices (formerly Linear Technology) is a single, rail-to-rail input and output operational amplifier optimized for high-speed, low-voltage signal conditioning. It delivers 350 V/µs slew rate, 320 MHz –3dB bandwidth at unity gain, 180 MHz gain-bandwidth product (AV ≥ 10), and ±85 mA output current - enabling precise driving of ADC inputs, active filters, and video line drivers in 2.5V–12.6V systems.
For engineers reviewing the LT1809IS6#TRMPBF datasheet, LT1809IS6#TRMPBF pinout, LT1809IS6#TRMPBF application, or LT1809IS6#TRMPBF equivalent, key selection criteria include its shutdown capability, 6-pin SOT-23 package with standard op amp pinout, –90 dBc distortion at 5 MHz, rail-to-rail swing within 20 mV of supplies, and guaranteed operation from –40°C to 85°C.
Technical Context
The LT1809IS6#TRMPBF employs a complementary bipolar input stage enabling rail-to-rail common-mode input range (V– to V+) and output swing to within 20 mV of either rail. Its fast-settling architecture supports 0.1% settling in 27 ns (2V step, AV = –1, RL = 500 Ω) and maintains low distortion (–90 dBc at 5 MHz) under heavy capacitive loads when stabilized with series output resistance.
It integrates a dedicated SHDN pin (logic-compatible, VL ≤ 0.3 V, VH ≥ VS – 0.5 V) enabling <1.3 mA shutdown current and sub-100 ns turn-on/off times. The device operates across ±2.5V to ±6.3V dual supplies or 2.5V–12.6V single supplies, with PSRR of 87 dB and CMRR of 89 dB at 25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 180 MHz (AV ≥ 10): enables stable closed-loop gain ≥10 up to ~18 MHz without peaking. |
| Slew Rate | 350 V/µs: supports full-scale 4 VPP output at >20 MHz without slewing-induced distortion. |
| –3dB Bandwidth | 320 MHz (AV = 1): suitable for unity-gain buffer applications requiring wide small-signal bandwidth. |
| Output Current | ±85 mA: drives 100 Ω loads directly, eliminating need for external buffers in video or DAC output stages. |
| THD @ 5 MHz | –90 dBc: meets SNR requirements for 12-bit, 10 MSPS data acquisition systems. |
| Supply Range | 2.5 V to 12.6 V: compatible with 3.3 V, 5 V, and ±5 V systems without level-shifting circuitry. |
| Operating Temp | –40°C to +85°C: qualified for industrial and automotive under-hood sensor signal conditioning. |
Pinout & Package
LT1809IS6#TRMPBF is housed in a 6-lead plastic TSOT-23 (ThinSOT™) package, 1 mm profile, with industry-standard op amp pinout. Pin 1 is OUT, Pin 2 is V–, Pin 3 is +IN, Pin 4 is –IN, Pin 5 is SHDN, and Pin 6 is V+.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT (Pin 1) | Amplifier output | Delivers rail-to-rail swing (within 20 mV of rails) and ±85 mA drive into resistive or moderate capacitive loads. |
| V– (Pin 2) | Negative supply | Reference for internal biasing; thermal pad connection point in TSOT-23; requires PCB copper for θJA = 145°C/W. |
| +IN (Pin 3) | Non-inverting input | Accepts signals from V– to V+; enables true rail-to-rail input stage operation without phase reversal. |
| –IN (Pin 4) | Inverting input | Supports precision feedback networks; matched input bias current shift (<2.5 mV over full common-mode range). |
| SHDN (Pin 5) | Shutdown control | Active-low logic input; pulls supply current to <1.3 mA while maintaining high-impedance output state. |
| V+ (Pin 6) | Positive supply | Accepts up to 12.6 V total supply voltage; powers internal bias and output stage; referenced for SHDN high threshold (VS – 0.5 V). |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Input common-mode range extends from V– to V+; output swings to within 20 mV of either rail - maximizes dynamic range in low-voltage (3 V) systems. |
| Integrated shutdown | Dedicated SHDN pin reduces quiescent current to <1.3 mA with <100 ns wake-up latency - ideal for power-cycled sensor front-ends. |
| Low distortion at high frequency | –90 dBc THD at 5 MHz ensures fidelity in ADC driver and video line driver applications where harmonic content degrades ENOB. |
| High output drive | ±85 mA short-circuit current enables direct drive of 150 Ω video loads or 100 Ω ADC input networks without external buffers. |
| Wide supply flexibility | Operates from 2.5 V single supply to ±6.3 V dual supply - simplifies design reuse across 3.3 V, 5 V, and ±5 V platforms. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4897-1ARJZ-R7 | Lower noise (1 nV/√Hz vs 16 nV/√Hz), lower supply current (11 mA vs 17 mA), no shutdown pin. | Better suited for low-noise preamp stages; unsuitable where power cycling or space-constrained shutdown is required. | Select ADA4897-1 if noise dominates system budget and shutdown is unnecessary; avoid if board-level power sequencing mandates shutdown control. |
| OPA837IDBVR | Higher slew rate (560 V/µs), wider GBW (310 MHz), but only specified down to –40°C in SO-8 - no SOT-23 variant available. | Enables >25 MHz closed-loop bandwidth; incompatible with footprint-constrained designs requiring 6-pin SOT-23. | Select OPA837 if bandwidth >20 MHz is mandatory and SO-8 layout is acceptable; avoid if TSOT-23 footprint or industrial temp grade is required. |
Compared with ADA4897-1ARJZ-R7 and OPA837IDBVR, the LT1809IS6#TRMPBF uniquely combines SOT-23 packaging, integrated shutdown, –40°C to +85°C qualification, and proven –90 dBc distortion at 5 MHz - making it the optimal choice for space- and power-constrained industrial ADC driver applications.

FAQ
What is the maximum supply voltage for LT1809IS6#TRMPBF?
The LT1809IS6#TRMPBF has an absolute maximum total supply voltage (V+ to V–) rating of 12.6 V. Operation beyond this voltage risks permanent damage. For reliable long-term use, the recommended maximum is 12.0 V across the supply rails, consistent with its specified 2.5 V to 12.6 V operating range and thermal limits in the 6-lead TSOT-23 package.
Does LT1809IS6#TRMPBF support rail-to-rail input and output simultaneously?
Yes, the LT1809IS6#TRMPBF supports rail-to-rail input common-mode range (V– to V+) and rail-to-rail output swing (within 20 mV of either supply rail) simultaneously. This is confirmed in the datasheet's "Description" section and electrical characteristics tables, enabling full dynamic range utilization in low-voltage (e.g., 3 V) single-supply systems without clipping or headroom loss.
What is the typical THD performance of LT1809IS6#TRMPBF at 5 MHz?
The LT1809IS6#TRMPBF achieves –90 dBc total harmonic distortion (THD) at 5 MHz under standard test conditions (AV = 1, RL = 1 kΩ, VO = 2 VP-P, VS = ±5 V). This value is explicitly listed in the "Features" section and verified in Figure 1b (Distortion vs Frequency) of the datasheet, confirming suitability for high-fidelity 12-bit data acquisition and video signal paths.
How does the SHDN pin function on LT1809IS6#TRMPBF?
The SHDN pin on LT1809IS6#TRMPBF is an active-low logic input. When pulled ≤0.3 V, it reduces supply current to <1.3 mA while placing the output in a high-impedance state. Turn-on time is 80 ns and turn-off time is 50 ns (RL = 100 Ω), enabling rapid power cycling in battery-operated systems. The pin accepts voltages up to VS – 0.5 V as a valid logic high.
Is LT1809IS6#TRMPBF pin-compatible with other SOT-23 op amps?
The LT1809IS6#TRMPBF uses the industry-standard 6-pin SOT-23 op amp pinout (OUT, V–, +IN, –IN, SHDN, V+), matching the physical layout of many single op amps including the LT1360, ADA4807-1, and OPA355. However, functional compatibility depends on electrical specifications - notably the presence of SHDN and rail-to-rail I/O - so direct substitution requires verification of gain stability, load drive, and shutdown behavior in the target circuit.
