Product details
Overview
LTC6241HVCS8#PBF from Analog Devices (formerly Linear Technology) is a dual, rail-to-rail output, low-noise CMOS operational amplifier optimized for precision signal conditioning in ±5V and single-supply systems. It delivers 18MHz gain bandwidth, 10V/μs slew rate, 550nVP-P 0.1Hz–10Hz noise, ≤125μV max input offset voltage (0°C to 70°C), and 1pA max input bias current - enabling high-fidelity amplification in photodiode interfaces and medical sensor front-ends.
For engineers reviewing the LTC6241HVCS8#PBF datasheet, LTC6241HVCS8#PBF pinout, LTC6241HVCS8#PBF application, or LTC6241HVCS8#PBF equivalent, key selection criteria include its HV-grade ±5.5V supply capability, SO-8 package compatibility with guard-ring PCB layouts, guaranteed 1pA input bias current over temperature, and rail-to-rail output swing within 30mV of rails at 1mA load.
Technical Context
The LTC6241HVCS8#PBF implements a unity-gain-stable CMOS input stage with ultra-low input capacitance (3.5pF differential, 3pF common-mode) and high input resistance (>1012Ω), enabling stable operation with high-impedance sources like piezoelectric sensors and photodiodes. Its internal architecture supports full-swing operation from V– to V+ – 30mV while maintaining >80dB CMRR over 0V to 3.5V common-mode range.
Designed for HV operation up to ±5.5V total supply (11V), it maintains specified performance across 2.8V to 11V supply range, with PSRR >85dB and AVOL >775 V/mV (RL = 10kΩ) under ±5V conditions. The dual amplifier topology allows matched-channel configurations without external trimming, supported by channel-to-channel VOS match ≤300μV (0°C to 70°C).
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 filter buffering. |
| Input Offset Voltage | ≤125μV max (0°C to 70°C) - reduces DC error in precision transducer amplifiers without nulling circuitry. |
| Input Bias Current | ≤1pA max - preserves signal integrity in >1GΩ source impedance applications (e.g., pH electrodes, photodiodes). |
| 0.1Hz–10Hz Noise | 550nVP-P - ensures minimal low-frequency drift in medical ECG/EEG front-ends and strain gauge bridges. |
| Supply Voltage Range | 2.8V to ±5.5V - supports bipolar operation in industrial control I/O modules and single-supply data acquisition systems. |
| Output Swing | Within 30mV of rails at 1mA - maximizes dynamic range in 3.3V/5V ADC driver stages with minimal headroom loss. |
| Slew Rate | 10V/μs - sustains <1% distortion for 1VP-P signals up to ~1.6MHz (FPBW = SR/πVP-P). |
Pinout & Package
Package: 8-lead plastic SO (SO-8), RoHS-compliant, lead-free finish. Thermal resistance θJA = 190°C/W. Pin 1 marked with dot; pin numbering follows standard SO-8 convention (counterclockwise from top-left corner).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

FAQ
What is the maximum supply voltage for LTC6241HVCS8#PBF?
The LTC6241HVCS8#PBF supports a total supply voltage up to 12V, enabling operation from ±5.5V rails or single supplies up to 12V. Absolute maximum ratings specify V+ to V– ≤12V, with guaranteed performance from 2.8V to ±5.5V per the datasheet's HV grade specifications. Exceeding 12V risks permanent damage.
Does LTC6241HVCS8#PBF require external compensation for unity-gain stability?
No, the LTC6241HVCS8#PBF is internally compensated for unity-gain stability and remains stable driving capacitive loads up to 5pF without external components. This eliminates the need for isolation resistors in ADC driver or photodiode transimpedance configurations, simplifying layout and reducing component count.
How does the input bias current of LTC6241HVCS8#PBF compare to standard CMOS op amps?
The LTC6241HVCS8#PBF guarantees ≤1pA maximum input bias current over 0°C to 70°C - significantly lower than typical CMOS op amps (often 10–100pA). This enables accurate amplification of nanoamp-level currents from photodiodes or ion-selective electrodes without introducing measurable offset error.
Can LTC6241HVCS8#PBF be used in single-supply 3.3V systems?
Yes, the LTC6241HVCS8#PBF operates down to 2.8V total supply, making it fully compatible with 3.3V single-supply systems. Its rail-to-rail output swings within 30mV of both rails at 1mA, delivering >3.2V of usable dynamic range - ideal for interfacing with 12-bit+ SAR ADCs powered from the same 3.3V rail.
What is the guaranteed input offset voltage specification for LTC6241HVCS8#PBF?
The LTC6241HVCS8#PBF has a guaranteed maximum input offset voltage of 125μV over the 0°C to 70°C operating temperature range. At –40°C to 85°C, the limit increases to 300μV, and at –40°C to 125°C (H-grade), it is 400μV - all explicitly specified in the device's electrical characteristics tables.
