Product details
Overview
LTC6242HVHGN#PBF from Analog Devices (formerly Linear Technology) is a quad, rail-to-rail output, low-noise CMOS operational amplifier optimized for precision signal conditioning in high-impedance, low-power, and wide-supply applications. It delivers 18MHz gain bandwidth, 10V/μs slew rate, 550nVP-P 0.1Hz–10Hz noise, 125μV max input offset voltage, and operates from ±5V supplies with H-grade temperature range (–40°C to +125°C). It is used in medical instrumentation front-ends and photodiode transimpedance amplifiers.
For engineers reviewing the LTC6242HVHGN#PBF datasheet, LTC6242HVHGN#PBF pinout, LTC6242HVHGN#PBF application, or LTC6242HVHGN#PBF equivalent, key selection criteria include guaranteed ±5V operation, 1pA max input bias current, rail-to-rail output swing within 30mV of rails, 16-pin SSOP package compatibility, and quad-channel channel matching performance across industrial temperature extremes.
Technical Context
The LTC6242HVHGN#PBF implements a fully differential CMOS input stage with ultra-low input bias current (≤1pA) and low input capacitance (3.5pF differential), enabling stable operation with high-Z sensors and piezoelectric transducers. Its unity-gain-stable architecture supports fast settling (900ns to 0.1%) and full-power bandwidth up to 1.06MHz at 3VP-P output into 1kΩ.
It features matched internal amplifier pairs with ≤400μV channel-to-channel VOS mismatch over –40°C to +125°C, CMRR ≥78dB (–5V ≤ VCM ≤ 3.5V), and PSRR ≥83dB under ±5V supply conditions - critical for rejecting supply-induced errors in battery-powered or mixed-signal systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad low-noise op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OP4177ARUZ | Lower 1kHz noise (2.8nV/√Hz vs 7–10nV/√Hz), but higher input bias (±2nA) and no ±5V guarantee; 12V max supply only. | Better for low-frequency precision DC apps; unsuitable for pA-level photodiode or pH sensing. | Select when ultra-low broadband noise dominates design priority and input impedance >100MΩ is acceptable. |
| ADA4522-4ARUZ | Zero-drift architecture; 0.025μV/°C drift vs 2.5μV/°C; but 5.5MHz GBW and 1.2V/μs slew rate limit speed-critical uses. | Ideal for DC-coupled thermocouple or bridge sensor amps where long-term drift matters more than bandwidth. | Choose when offset drift <0.1μV/°C is mandatory and 18MHz bandwidth is unnecessary. |
Compared with OP4177ARUZ and ADA4522-4ARUZ, the LTC6242HVHGN#PBF uniquely balances picoampere input bias, 18MHz bandwidth, ±5V operation, and H-grade temperature range - making it the only option for high-speed, high-impedance, wide-temperature industrial and medical signal chains requiring all four attributes simultaneously.

FAQ
What is the maximum supply voltage for the LTC6242HVHGN#PBF?
The LTC6242HVHGN#PBF supports a total supply voltage of up to 12V, enabling operation from ±5V rails (10V total) with 1V headroom. Absolute maximum ratings specify V+ to V– ≤ 12V, and operation is fully characterized from ±5V (VS = ±5V) across the full –40°C to +125°C range. Exceeding ±5.5V risks violating guaranteed specifications.
Does the LTC6242HVHGN#PBF require external compensation for unity-gain stability?
No, the LTC6242HVHGN#PBF is internally compensated for unity-gain stability across its full operating range. It maintains ≥60° phase margin with 5pF load capacitance and 1kΩ load at ±5V supply, as verified in the datasheet's Gain Bandwidth and Phase Margin vs Temperature plot (Figure G13). No external compensation components are needed for standard configurations.
How does the input bias current of the LTC6242HVHGN#PBF behave over temperature?
The LTC6242HVHGN#PBF guarantees ≤1pA maximum input bias current from –40°C to +125°C. At 25°C, typical IB is 0.2pA; at 125°C, it rises to ≤1pA (not nA). This ultra-stable pA-level bias is enabled by proprietary CMOS input protection and is validated in Figure G10 of the datasheet, confirming minimal drift across the H-grade range.
Can the LTC6242HVHGN#PBF drive a 1000pF capacitive load directly?
The LTC6242HVHGN#PBF is not optimized for direct 1000pF capacitive loads. Datasheet testing confirms stability with ≤5pF load capacitance at unity gain. Driving larger capacitive loads requires isolation via a series resistor (e.g., 100Ω) or a dedicated buffer stage. Uncompensated 1000pF loads risk peaking, overshoot, or oscillation due to phase margin degradation.
What is the meaning of "HV" in the LTC6242HVHGN#PBF part number?
The "HV" suffix in LTC6242HVHGN#PBF denotes the high-voltage version, specifying guaranteed operation up to ±5V supplies (10V total) - unlike the standard LTC6242 which is rated only to 6V total (e.g., 3V/0V or 5V/0V). The HV variant also extends common-mode input range to –5V and improves PSRR to 83dB under ±5V conditions.
