Product details
Overview
LTC6240HVHS5#TRPBF from Analog Devices (formerly Linear Technology) is a single-channel, rail-to-rail output, low-noise CMOS operational amplifier optimized for high-precision, high-impedance signal conditioning. It delivers 18MHz gain bandwidth, 10V/μs slew rate, 550nVP-P (0.1Hz–10Hz) input noise, ≤1pA max input bias current, and operates on supplies up to ±5.5V - enabling use in photodiode amplifiers, medical front-ends, and industrial sensor interfaces.
For engineers reviewing the LTC6240HVHS5#TRPBF datasheet, LTC6240HVHS5#TRPBF pinout, LTC6240HVHS5#TRPBF application, or LTC6240HVHS5#TRPBF equivalent, key selection criteria include its H-grade (–40°C to 125°C) temperature rating, HV-series extended supply range (±5.5V), ultra-low input bias current, and SOT-23-5 package compatibility with guard-ring PCB layouts.
Technical Context
The LTC6240HVHS5#TRPBF employs a proprietary CMOS input stage with guarded input traces and low-capacitance design (3.5pF differential input capacitance), enabling stable operation with high-source-impedance sensors. Its unity-gain-stable architecture supports direct connection to capacitive transducers without external compensation.
It features an output stage capable of swinging within 30mV of either rail under 5mA load, and full specification across ±5V supplies - distinguishing it from standard LTC6240 variants limited to 6V total supply. Input common-mode range extends to the negative rail, supporting single-supply operation down to 2.8V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 18MHz - enables stable closed-loop gain ≥10 at 1.8MHz or ≥2 at 9MHz for anti-aliasing or signal reconstruction. |
| Input Bias Current | ≤1pA max (–40°C to 125°C) - preserves signal integrity in >1GΩ source impedance circuits like photodiode or pH electrode interfaces. |
| 0.1Hz–10Hz Noise | 550nVP-P - critical for DC-coupled precision measurement where low-frequency drift dominates error budget. |
| Input Offset Voltage | 175μV max (–40°C to 125°C) - ensures <0.5% gain error in 12-bit systems with 1V full-scale input. |
| Supply Range | 2.8V to ±5.5V - supports dual-rail operation in ±5V legacy systems and single-rail 3V/5V embedded designs without level-shifting. |
| Slew Rate | 10V/μs - allows clean 1VP-P output at 1.5MHz without slewing distortion in fast-settling data acquisition paths. |
| Operating Temperature | –40°C to 125°C - qualified for under-hood automotive, industrial motor control, and aerospace power supply monitoring. |
Pinout & Package
LTC6240HVHS5#TRPBF is housed in a 5-lead plastic TSOT-23 (ThinSOT™) package, 1mm height, lead-free, tape-and-reel. The package supports PCB guard ring implementation around the inverting input to minimize leakage currents in ultra-high-impedance applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier Output | Capable of rail-to-rail swing (within 30mV of V+ or V– at 5mA), drives 1kΩ loads directly without buffering. |
| 2 (V–) | Negative Supply Rail | Reference for internal biasing; underside metal pad (in some variants) may be connected to V– for thermal/EMI improvement. |
| 3 (+IN) | Non-Inverting Input | High-impedance CMOS node (1012Ω); requires guard ring routing to maintain sub-pA leakage performance. |
| 4 (–IN) | Inverting Input | Differential input node; matched to +IN for CMRR >80dB; sensitive to stray capacitance due to 3.5pF CIN. |
| 5 (V+) | Positive Supply Rail | Accepts up to +5.5V (or –5.5V when used in dual-supply configuration); PSRR >85dB minimizes supply noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full dynamic range in low-voltage (3V) or split-supply (±5V) systems - maximizes ADC utilization without level-shifting. |
| Ultra-low 0.1Hz–10Hz noise | 550nVP-P enables stable DC measurements in weigh scales, thermopile amplifiers, and electrochemical sensors. |
| Guaranteed ≤1pA IB over temperature | Ensures predictable bias error in high-Z transducer interfaces across automotive and industrial ambient ranges. |
| H-grade temperature qualification | Specified from –40°C to 125°C - eliminates derating concerns in engine control units, power inverters, and downhole instrumentation. |
| Low input capacitance (3.5pF) | Reduces phase lag and peaking with capacitive sources (e.g., piezoelectric sensors), improving stability without added compensation. |
Applications
| Photodiode Amplifier | Medical ECG Front-End |

IC Role / Device Role / Timing Role: Low-noise, high-CMRR instrumentation amplifier input stage with AC-coupled input and DC servo loop. Use Value: 83dB CMRR (–5V ≤ VCM ≤ 3.5V) rejects power-line interference; rail-to-rail output drives 12-bit SAR ADC directly. |
| Industrial Pressure Sensor Signal Chain | High-Voltage Power Supply Monitor |
Use Scenario: Amplification of mV-level bridge outputs from MEMS pressure sensors in HVAC and process control systems. IC Role / Device Role / Timing Role: Precision gain stage with programmable offset correction and 2.8V–6V single-supply operation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise, rail-to-rail output op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC6240HS5#TRPBF | Same package and H-grade temp range, but standard supply range (2.8V–6V) - no ±5.5V support. | Not suitable for dual-supply ±5V systems requiring headroom beyond 6V total; limited to single-rail or lower-voltage split-rail. | Select only if supply is strictly ≤6V and ±5.5V operation is unnecessary. |
| ADA4522-1ARZ-R7 | Zero-drift architecture; 0.3μV max VOS, 5.8nV/√Hz noise at 1kHz, but 2.2MHz GBW and 1.8V/μs slew rate. | Better DC precision and drift, but insufficient speed for >100kHz signal conditioning; higher quiescent current (1.2mA vs 2.4mA). | Prefer for ultra-low-offset DC applications (e.g., strain gauge bridges); avoid where bandwidth >5MHz or slew >5V/μs is required. |
Compared with LTC6240HS5#TRPBF and ADA4522-1ARZ-R7, the LTC6240HVHS5#TRPBF uniquely balances 18MHz bandwidth, ±5.5V operation, and sub-pA bias current - making it the only option among the three qualified for high-speed, high-common-mode, high-impedance sensing in harsh environments.

FAQ
What is the maximum supply voltage for LTC6240HVHS5#TRPBF?
The LTC6240HVHS5#TRPBF supports a total supply voltage of up to 12V, enabling operation on ±5.5V rails. This distinguishes it from the standard LTC6240 series (max 7V), and is explicitly guaranteed in the Absolute Maximum Ratings table for the HV variant. Exceeding ±5.5V risks permanent damage.
Does LTC6240HVHS5#TRPBF support rail-to-rail input common-mode range?
No - the LTC6240HVHS5#TRPBF has rail-to-rail *output* swing but only extends its input common-mode range to the negative supply rail (V–). For ±5V operation, VCM is specified from –5V to +3.5V. It does not accept inputs beyond V+ – 1.5V, unlike true rail-to-rail input op amps.
Is the 1pA input bias current guaranteed over temperature for LTC6240HVHS5#TRPBF?
Yes - the datasheet guarantees ≤1pA maximum input bias current for LTC6240HVHS5#TRPBF across its full operating temperature range of –40°C to 125°C (H-grade). This is confirmed in the Electrical Characteristics tables for LTC6240H/LTC6240HVH, with typical value of 0.5pA at 25°C and 1pA max at 125°C.
Can LTC6240HVHS5#TRPBF drive a 1000pF capacitive load stably?
No - the LTC6240HVHS5#TRPBF is unity-gain stable into purely resistive loads, but capacitive loads >100pF require isolation resistance (e.g., 10–50Ω in series with output) or feedback capacitor compensation. The Typical Performance Characteristics show phase margin degradation above 100pF; driving 1000pF directly risks oscillation or overshoot.
What is the purpose of the exposed metal pad on the bottom of the TSOT-23 package for LTC6240HVHS5#TRPBF?
The underside metal pad on the LTC6240HVHS5#TRPBF's TSOT-23 package is internally connected to V–. While optional per datasheet, connecting it to the PCB's V– plane improves thermal dissipation (reducing θJA) and lowers output noise by providing a low-inductance return path - especially beneficial in low-noise, high-gain configurations.
