Product details
Overview
LTC6241HVIDD#TRPBF from Analog Devices (formerly Linear Technology) is a dual, rail-to-rail output, low-noise CMOS operational amplifier optimized for precision signal conditioning in high-impedance sensor interfaces and medical instrumentation. It delivers 18MHz gain bandwidth, 10V/μs slew rate, 550nVP-P 0.1Hz–10Hz noise, 125μV max input offset voltage, and 0.2pA typical input bias current at 25°C - enabling accurate amplification of weak signals from photodiodes or piezoelectric transducers.
For engineers reviewing the LTC6241HVIDD#TRPBF datasheet, LTC6241HVIDD#TRPBF pinout, LTC6241HVIDD#TRPBF application, or LTC6241HVIDD#TRPBF equivalent, key selection criteria include guaranteed 1pA max input bias current over –40°C to 85°C, ±5V supply compatibility, 8-pin 3mm × 3mm DFN package with underside thermal pad, and channel-to-channel matching performance critical for differential signal paths.
Technical Context
The LTC6241HVIDD#TRPBF implements a unity-gain-stable CMOS input stage with ultra-low input capacitance (3.5pF differential, 3pF common-mode) and rail-to-rail output swing within 30mV of either supply rail. Its architecture supports stable operation on single supplies as low as 2.8V or split supplies up to ±5.5V, with input common-mode range extending to the negative rail.
It features matched internal amplifier pairs with guaranteed channel-to-channel VOS match ≤300μV and CMRR match ≥76dB over temperature, making it suitable for precision instrumentation-grade differential amplifiers and active filters where tracking between channels is essential.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 18MHz - enables stable closed-loop gain up to ~100 at 180kHz, supporting wideband sensor signal conditioning. |
| Input Bias Current | 0.2pA typ / 1pA max (–40°C to 85°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 medical front-ends and precision weigh scales. |
| Input Offset Voltage | 125μV max (–40°C to 85°C) - reduces initial error in 16-bit+ data acquisition systems without trimming. |
| Slew Rate | 10V/μs - supports fast settling for pulse-amplified signals in time-of-flight or ultrasonic receivers. |
| Supply Range | 2.8V to ±5.5V - allows direct interface with 3.3V logic, ±5V analog rails, or battery-powered portable instruments. |
| Output Swing | Within 30mV of rails - maximizes dynamic range in low-voltage systems, e.g., 3.3V ADC drivers. |
Pinout & Package
Package: 8-lead (3mm × 3mm) plastic DFN with underside metal pad connected to V– (PCB connection optional). Thermal resistance θJA = 43°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads up to 10mA; rail-to-rail swing enables full-scale utilization of downstream ADCs. |
| 2 | –IN A | Inverting input of Amp A - high-impedance node requiring guard ring layout for leakage-sensitive applications. |
| 3 | +IN A | Non-inverting input of Amp A - referenced to system ground or bias network; matches +IN B for common-mode rejection. |
| 4 | V– | Negative supply rail - also connects to underside thermal pad; must be low-impedance for noise immunity and thermal stability. |
| 5 | V+ | Positive supply rail - decoupling capacitor required within 1cm for high-frequency PSRR maintenance. |
| 6 | OUT B | Amplifier B output - electrically isolated but thermally coupled to OUT A; enables dual-path signal processing on one die. |
| 7 | –IN B | Inverting input of Amp B - matched to –IN A for differential pair configurations; same layout rules apply. |
| 8 | +IN B | Non-inverting input of Amp B - used with external resistors to configure instrumentation amp topologies or matched filter stages. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low input bias current | 0.2pA typical ensures <1μV error from 1GΩ source impedance at 25°C - critical for photodiode and pH electrode interfaces. |
| Rail-to-rail output stage | Swings within 30mV of V+ and V–, delivering >98% of supply voltage range to 10kΩ loads - maximizes SNR in low-voltage data acquisition. |
| Low 1/f noise | 550nVP-P (0.1Hz–10Hz) minimizes baseline wander in ECG and EEG amplifiers without AC coupling or chopper stabilization. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-noise op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4625-2ARZ-R7 | Higher 3.2nV/√Hz noise density (vs. 7nV/√Hz), 2.8MHz GBW, 1.2pA IB max at 125°C - wider temp range but lower speed/noise performance. | Preferred for extended industrial temp (–40°C to 125°C) where 18MHz bandwidth is not required. | Select when operating above 85°C ambient or when higher PSRR (130dB) outweighs noise/bandwidth needs. |
| OPA2189IDR | Zero-drift architecture (0.003μV/°C drift), 5.2nV/√Hz noise, 12MHz GBW, 20pA IB - superior offset stability but higher current noise limits high-Z use. | Better for DC-precision applications (e.g., strain gauge bridges) where long-term drift dominates over 1/f noise. | Choose when microvolt-level offset drift over temperature/time is more critical than sub-picoamp input bias. |
Compared with ADA4625-2ARZ-R7 and OPA2189IDR, the LTC6241HVIDD#TRPBF uniquely balances ultra-low input bias current (1pA max), 18MHz bandwidth, and 550nVP-P low-frequency noise - making it optimal for high-impedance, wideband, precision analog front-ends where all three parameters are simultaneously constrained.

FAQ
What is the maximum input bias current specification for LTC6241HVIDD#TRPBF over its full operating temperature range?
The LTC6241HVIDD#TRPBF guarantees a maximum input bias current of 1pA over its specified operating temperature range of –40°C to 85°C. This value is explicitly stated in the "ELECTRICAL CHARACTERISTICS" table for the LTC6241HVC/I grade under the IB parameter, and applies to both SO-8 and DFN packages including the LTC6241HVIDD#TRPBF variant.
Does LTC6241HVIDD#TRPBF support ±5V dual-supply operation?
Yes, the LTC6241HVIDD#TRPBF supports dual-supply operation up to ±5.5V. The datasheet specifies "Supply Operation: 2.8V to ±5.5V" for the HV versions (LTC6241HVxxx), and the HVI suffix in LTC6241HVIDD#TRPBF confirms inclusion of the HV feature set - verified by the "AVAILABLE OPTIONS" table listing "3V, 5V, ±5V" under Specified Supply Voltage for this part number.
What is the guaranteed 0.1Hz to 10Hz input noise voltage for LTC6241HVIDD#TRPBF?
The guaranteed 0.1Hz to 10Hz input noise voltage for LTC6241HVIDD#TRPBF is 550nVP-P. This value is explicitly listed in the "FEATURES" section and repeated in multiple "ELECTRICAL CHARACTERISTICS" tables across supply conditions (5V, 3V, ±5V) and temperature grades, confirming it applies to the HVI grade in DFN packaging.
Is the underside thermal pad of the LTC6241HVIDD#TRPBF package required to be soldered to PCB ground?
No, the underside metal pad of the LTC6241HVIDD#TRPBF DFN package is connected to V– internally, and the datasheet states "PCB connection optional". While connecting it improves thermal performance (θJA = 43°C/W assumes connection), electrical functionality is maintained without soldering - though thermal derating and reliability under sustained load benefit from thermal pad attachment.
What is the minimum supply voltage for reliable operation of LTC6241HVIDD#TRPBF?
The minimum supply voltage for LTC6241HVIDD#TRPBF is 2.8V total supply (i.e., V+ – V– ≥ 2.8V), as confirmed in the "ABSOLUTE MAXIMUM RATINGS" and "ELECTRICAL CHARACTERISTICS" sections. This applies across all supply configurations - single-ended (e.g., 2.8V to 6V) or split (e.g., ±1.4V minimum), and is guaranteed over the full –40°C to 85°C operating range.
