Product details
Overview
LTC6240HVHS8#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 in ±5V supply systems. It delivers 18MHz gain bandwidth, 10V/μs slew rate, 550nVP-P 0.1Hz–10Hz noise, ≤1pA max input bias current, and operates across –40°C to +125°C - enabling use in photodiode amplifiers, medical sensor front-ends, and industrial instrumentation.
For engineers reviewing the LTC6240HVHS8#TRPBF datasheet, LTC6240HVHS8#TRPBF pinout, LTC6240HVHS8#TRPBF application, or LTC6240HVHS8#TRPBF equivalent, key selection criteria include guaranteed ±5V operation, H-grade temperature range, SO-8 package with guard-ring-compatible layout, and sub-1pA input bias current at 125°C - critical for charge-sensitive and ultra-high-Z transducer interfaces.
Technical Context
The LTC6240HVHS8#TRPBF implements a complementary CMOS input stage with matched P- and N-channel MOSFETs, enabling ultra-low input bias current (≤1pA max over temperature) and wide common-mode input range extending to the negative rail. Its unity-gain-stable architecture supports fast settling (900ns to 0.1%) and full-power bandwidth up to 1.06MHz at ±5V with 3VP-P output swing.
It features rail-to-rail output swing within 30mV of either supply rail under load, low input capacitance (3.5pF differential), and high open-loop gain (≥775 V/mV at ±5V) - making it suitable for precision transimpedance and active filter designs where DC accuracy and dynamic range must coexist.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 18MHz - enables stable closed-loop operation up to ~16MHz at unity gain with minimal phase margin degradation. |
| Input Bias Current | ≤1pA max (–40°C to +125°C) - preserves signal integrity in >1GΩ source impedance applications like photodiode amps. |
| 0.1Hz–10Hz Noise | 550nVP-P - ensures minimal low-frequency drift in DC-coupled sensor interfaces and precision integrators. |
| Input Offset Voltage | ≤450μV max (–40°C to +125°C) - supports accurate amplification of mV-level signals without trimming. |
| Slew Rate | 10V/μs - sustains 1.06MHz full-power bandwidth at 3VP-P, suitable for fast pulse conditioning. |
| Supply Range | ±2.8V to ±5.5V (12V total) - supports bipolar operation in legacy industrial and test equipment rails. |
| Operating Temperature | –40°C to +125°C (H-grade) - qualified for under-hood automotive, downhole, and industrial control environments. |
Pinout & Package
Package: 8-lead plastic SO (SO-8), lead-free, tape-and-reel. Thermal resistance θJA = 190°C/W. Pin 1 marked by notch or dot; pin numbering follows standard SO-8 convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC) | No Connect | Internally unused; no PCB connection required - allows guard ring routing on sensitive analog layouts. |
| 2 (V–) | Negative Supply Rail | Reference for internal biasing; connects to system ground or negative supply; underside metal optional tie to V–. |
| 3 (+IN) | Inverting Input | Differential input node with 3.5pF differential input capacitance - requires careful layout to minimize capacitive coupling errors. |
| 4 (–IN) | Non-Inverting Input | High-impedance CMOS input (≥1TΩ); common-mode range extends to V– - enables single-supply sensing with level-shifting. |
| 5 (OUT) | Amplifier Output | Rail-to-rail output capable of sourcing/sinking ≥10mA; swings within 30mV of rails at light loads. |
| 6 (NC) | No Connect | Internally unused; may be left floating or grounded for mechanical stability - no electrical function. |
| 7 (NC) | No Connect | Internally unused; same as Pin 1 and Pin 6 - no signal or power role. |
| 8 (V+) | Positive Supply Rail | Connects to +5V (or +5.5V max); PSRR ≥85dB ensures immunity to supply ripple in noisy environments. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise, rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4522-1ARZ | Zero-drift architecture; 0.3μV max VOS, but higher 1/f noise (1.5μVP-P) and 2.2mA supply current. | Better DC accuracy for static measurements; less suitable for AC-coupled low-frequency biosignal amplification. | Select when offset drift dominates performance budget; avoid when 0.1Hz–10Hz noise is critical. |
| OPA377AIDR | Lower GBW (9MHz), higher input bias (0.2pA typ but not specified max over temp), SO-8 package. | Cost-optimized for consumer-grade instrumentation; lacks H-grade temp rating and ±5V guarantee. | Select for commercial-temp, lower-bandwidth applications where 125°C operation and bipolar supply are unnecessary. |
Compared with ADA4522-1ARZ and OPA377AIDR, the LTC6240HVHS8#TRPBF uniquely balances ultra-low input bias current (≤1pA max over temperature), low 1/f noise (550nVP-P), and guaranteed ±5V operation in an H-grade SO-8 package - making it the only option among the three qualified for high-Z, wide-temperature, bipolar-rail sensor front-ends.

FAQ
What is the maximum guaranteed input bias current for LTC6240HVHS8#TRPBF over its full operating temperature range?
The LTC6240HVHS8#TRPBF guarantees ≤1pA maximum input bias current across its full –40°C to +125°C operating temperature range, as confirmed in the H-grade electrical characteristics table for the HV variant. This specification applies specifically to the SO-8 package and is validated per Note 7 in the datasheet, which states 100% testing at 25°C and guaranteed performance over temperature.
Does LTC6240HVHS8#TRPBF support true bipolar operation with ±5V supplies?
Yes, the LTC6240HVHS8#TRPBF is explicitly rated for ±5V operation (10V total supply), with absolute maximum ratings extending to ±5.5V. Electrical characteristics including gain bandwidth (13–18MHz), slew rate (5.5–10V/μs), and input common-mode range (–5V to +3.5V) are fully specified at ±5V, distinguishing it from standard LTC6240 variants limited to 2.8V–6V single-supply operation.
How does the LTC6240HVHS8#TRPBF differ from the standard LTC6240HS8#TRPBF?
The LTC6240HVHS8#TRPBF adds guaranteed operation at ±5V supply (up to 12V total), whereas the LTC6240HS8#TRPBF is rated only for 2.8V–6V single-supply operation. At ±5V, the HV version maintains higher large-signal gain (≥775 V/mV), improved PSRR (≥85dB), and wider input common-mode range (–5V to +3.5V) - all validated across –40°C to +125°C.
Is the SO-8 package of LTC6240HVHS8#TRPBF compatible with PCB guard ring layouts?
Yes - Pins 1, 6, and 7 of the LTC6240HVHS8#TRPBF are designated NC (no connect), enabling direct implementation of a continuous copper guard ring surrounding the +IN and –IN pins. This layout technique minimizes leakage paths and improves effective input impedance in high-precision transimpedance applications, as recommended in Linear's application notes for photodiode amplifiers.
What is the typical 1kHz input voltage noise density for LTC6240HVHS8#TRPBF?
The LTC6240HVHS8#TRPBF exhibits a typical input voltage noise density of 7nV/√Hz at 1kHz, with a guaranteed maximum of 10nV/√Hz. This value remains consistent across supply voltages (±5V, +5V, +3V) and is independent of temperature grade - confirming its suitability for medium-bandwidth precision amplification where broadband noise impacts SNR.
