Product details
Overview
LTC6240HVCS5#TRMPBF from Analog Devices (formerly Linear Technology) is a single-channel, rail-to-rail output, low-noise CMOS operational amplifier optimized for high-impedance, precision 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 ±5V - ideal for photodiode amplification and medical sensor front-ends.
For engineers reviewing the LTC6240HVCS5#TRMPBF datasheet, LTC6240HVCS5#TRMPBF pinout, LTC6240HVCS5#TRMPBF application, or LTC6240HVCS5#TRMPBF equivalent, key selection criteria include guaranteed 1pA max IB at 25°C, H-grade temperature range (–40°C to 125°C), 5-pin TSOT-23 package with guard ring capability, and HV-series supply tolerance (±5V).
Technical Context
The LTC6240HVCS5#TRMPBF employs a CMOS input stage with ultra-low input bias current and low input capacitance (3.5pF differential), enabling stable operation with high-source-impedance transducers. Its unity-gain-stable architecture supports fast settling (900ns to 0.1%) and full-power bandwidth up to 1.06MHz at ±5V.
It features rail-to-rail output swing within 30mV of either supply rail and an input common-mode range extending to the negative rail. The HV variant guarantees performance across ±5V supplies while maintaining low offset drift (2.5μV/°C max) and high CMRR (105dB).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 18MHz - enables stable closed-loop gain ≥10 at >1.8MHz or ≥100 at >180kHz |

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-R7 | Zero-drift architecture; 0.005μV/°C offset drift vs. 2.5μV/°C; higher supply current (1.2mA vs. 2.7mA typ at ±5V) | Better long-term DC stability but higher power; less suitable for battery-powered photodiode amps | Select for ultra-low drift requirements where power is secondary; verify layout compatibility with SOIC-8 footprint |
| OPA377AIDBVR | Lower GBW (9MHz); higher input bias current (0.2pA typ but not guaranteed ≤1pA); smaller 5-pin SOT-23 package | Cost-optimized alternative for non-critical industrial sensors; not rated for ±5V or 125°C operation | Choose for cost-sensitive, room-temperature applications where 1pA guarantee and HV supply are unnecessary |
Compared with ADA4522-1ARZ-R7 and OPA377AIDBVR, the LTC6240HVCS5#TRMPBF uniquely balances guaranteed 1pA max input bias, ±5V HV operation, and 125°C qualification - making it the only option among the three validated for high-reliability, high-impedance, wide-temperature analog front-ends.

FAQ
What is the maximum guaranteed input bias current for LTC6240HVCS5#TRMPBF?
The LTC6240HVCS5#TRMPBF guarantees ≤1pA maximum input bias current at 25°C, as specified in the Absolute Maximum Ratings and Electrical Characteristics tables. This value applies specifically to the LTC6240 (single version) in both S5 and S8 packages and is a defining feature distinguishing it from standard CMOS op amps. At –40°C to 125°C, typical IB remains below 1pA, though the max limit increases to 2.5nA per datasheet Section 12.
Does LTC6240HVCS5#TRMPBF support true dual-supply operation up to ±5V?
Yes, LTC6240HVCS5#TRMPBF is explicitly characterized and guaranteed for dual-supply operation up to ±5V (10V total). The "HV" suffix denotes the high-voltage variant, which extends the supply range beyond the standard LTC6240's 2.8V–6V limit. Absolute maximum ratings confirm total supply voltage up to 12V, and electrical specs (e.g., CMRR, GBW, VOS) are validated at ±5V in the HV-specific characterization sections.
What is the input common-mode voltage range for LTC6240HVCS5#TRMPBF at ±5V supplies?
At ±5V supplies, the LTC6240HVCS5#TRMPBF supports an input common-mode voltage range from –5V to +3.5V, as guaranteed by CMRR specifications. This means the inputs can be driven down to the negative rail (–5V) and up to 1.5V below the positive rail (+5V), enabling direct interfacing with bipolar sensor outputs and level-shifting circuits without external biasing.
Is LTC6240HVCS5#TRMPBF pin-compatible with other variants in the LTC6240 family?
Yes, LTC6240HVCS5#TRMPBF shares identical pinout and footprint with all other S5-package variants (e.g., LTC6240CS5#TRMPBF, LTC6240IS5#TRMPBF). All use the same 5-lead TSOT-23 configuration: OUT, V−, +IN, –IN, V+. This allows drop-in replacement across temperature grades (C/I/H) and voltage grades (standard/HV) without PCB redesign - provided system-level supply and thermal constraints are met.
What is the typical supply current for LTC6240HVCS5#TRMPBF at ±5V and 25°C?
The typical supply current for LTC6240HVCS5#TRMPBF is 3.3mA at ±5V and 25°C, as specified in the HV-grade Electrical Characteristics table (Section 9). This value reflects total quiescent current for the single amplifier. At –40°C to 125°C, supply current remains tightly bounded between 2.7mA (min) and 3.8mA (max), ensuring predictable power budgeting in thermally varied environments.
