Product details
Overview
LTC6242HVIGN#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 sensor interfaces. It delivers 18MHz gain bandwidth, 10V/μs slew rate, 550nVP-P 0.1Hz–10Hz noise, 125μV max input offset voltage, and operates on supplies up to ±5V - enabling high-fidelity amplification in medical instrumentation and photodiode front-ends.
For engineers reviewing the LTC6242HVIGN#PBF datasheet, LTC6242HVIGN#PBF pinout, LTC6242HVIGN#PBF application, or LTC6242HVIGN#PBF equivalent, key selection criteria include guaranteed ±5V operation, 1pA max input bias current at –40°C to 85°C, rail-to-rail output swing within 30mV of rails, low 1.9mA per amplifier supply current, and SSOP-16 package compatibility with guard ring PCB layouts.
Technical Context
The LTC6242HVIGN#PBF implements a unity-gain-stable CMOS input stage with 1012Ω input resistance and 3.5pF differential input capacitance, enabling stable operation with high-source-impedance transducers. Its output stage uses complementary common-drain topology to achieve rail-to-rail swing while maintaining 10V/μs slew rate under 1kΩ load.
Designed for dual-supply ±5V operation (total 10V), it maintains full AC performance across –40°C to 85°C, with guaranteed 13MHz minimum gain bandwidth and 5.5V/μs minimum slew rate over temperature - critical for time-domain integrity in charge-amplifier and active filter applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 18MHz typical - supports stable closed-loop gain ≥10 at 1.8MHz or ≥2 at 9MHz without compensation. |
| Input Offset Voltage | 125μV max (–40°C to 85°C) - enables DC-coupled amplification of mV-level sensor signals without nulling circuitry. |
| 0.1Hz–10Hz Noise | 550nVP-P - ensures sub-μV baseline stability in ECG and strain gauge front-ends. |
| Input Bias Current | 1pA max (–40°C to 85°C) - minimizes voltage error in >1GΩ photodiode or piezoelectric sensor interfaces. |
| Supply Range | ±5V (10V total) - allows direct interfacing with bipolar sensor outputs and legacy industrial signal chains. |
| Output Swing | Within 30mV of either rail - maximizes dynamic range in 3.3V or 5V single-supply systems using level-shifting. |
| Channel Count | Quad - integrates four matched amplifiers in one SSOP-16 package, reducing board area vs discrete solutions. |
Pinout & Package
The LTC6242HVIGN#PBF is housed in a 16-lead plastic SSOP (GN) package with exposed pad connected to V–. Pinout supports independent amplifier sections (A–D) with non-inverting/inverting inputs and outputs arranged for minimal crosstalk in multi-channel designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 | –IN A | Inverting input of Amp A - high-impedance node for feedback networks. |
| 3 | +IN A | Non-inverting input of Amp A - accepts DC-coupled sensor signals up to V–. |
| 4 | V+ | Positive supply rail - connects to +5V in ±5V operation or +10V in single-supply mode. |
| 5 | +IN B | Non-inverting input of Amp B - electrically isolated from Amp A inputs for differential pair routing. |
| 6 | –IN B | Inverting input of Amp B - matched to Amp A for common-mode rejection in instrumentation amps. |

| 13 | +IN C | Non-inverting input of Amp C - routed adjacent to V– for low-inductance grounding of high-impedance sources. |
| 14 | –IN C | Inverting input of Amp C - matched offset and drift to other channels for multi-stage filtering. |
| 15 | OUT C | Amplifier C output - shares same drive capability and noise floor as other outputs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC6242IGN#PBF | Same quad architecture but rated for 3V–6V single-supply only (no ±5V support); 1.9mA supply current vs 3.3mA at ±5V. | Suitable for battery-powered 5V systems where bipolar supply is unavailable; not usable in ±5V industrial signal chains. | Select when operating exclusively on 3–6V single supply and lower quiescent current is prioritized over bipolar flexibility. |
| ADA4898-4ARUZ | Higher 29MHz GBW and 1000V/mV open-loop gain, but 2.5pA input bias current and 1.2mA per amp supply current. | Better for wideband active filters requiring >20MHz closed-loop bandwidth; higher bias current limits use with >100MΩ sources. | Select when bandwidth >20MHz is required and sensor source impedance <100MΩ; avoid for ultra-high-Z photodiode applications. |
Compared with LTC6242IGN#PBF, the LTC6242HVIGN#PBF adds ±5V operation and higher slew rate (10V/μs vs 8.5V/μs) at the cost of 0.4mA higher per-amplifier current; versus ADA4898-4ARUZ, it trades 11MHz bandwidth for 2.3pA lower input bias current and better low-frequency noise - making it superior for DC-precision, high-impedance sensing.

FAQ
What is the maximum supply voltage rating for the LTC6242HVIGN#PBF?
The LTC6242HVIGN#PBF supports a total supply voltage of 12V, enabling operation on ±5V supplies (10V total) with 1V margin. Absolute maximum ratings specify V+ to V– ≤12V; exceeding this risks permanent damage. Operation at ±5V is fully characterized and guaranteed across –40°C to 85°C, distinguishing it from standard LTC6242 variants limited to 6V total supply.
Does the LTC6242HVIGN#PBF support rail-to-rail input common-mode range?
The LTC6242HVIGN#PBF supports rail-to-rail output swing but has limited input common-mode range: it extends to the negative rail (V–) but only to (V+ – 1.5V) at room temperature, or (V+ – 2V) over full temperature range. For example, at ±5V supply, input common-mode range is –5V to +3.5V - sufficient for most bipolar sensor interfaces but not true rail-to-rail input.
How does the input bias current of the LTC6242HVIGN#PBF compare to the standard LTC6242IGN#PBF?
The LTC6242HVIGN#PBF specifies 1pA maximum input bias current over –40°C to 85°C, identical to the standard LTC6242IGN#PBF. Both share the same CMOS input architecture and process; the "HV" suffix denotes extended supply voltage capability (±5V), not improved bias current. Typical bias current is 0.2pA at 25°C for both versions.
Can the LTC6242HVIGN#PBF be used in single-supply 5V applications?
Yes, the LTC6242HVIGN#PBF operates on single-supply 5V (V+ = 5V, V– = 0V) with full specification compliance. Its input common-mode range includes the negative rail (0V), and output swings within 30mV of both rails - enabling true 0–5V signal handling. The HV version's ±5V rating ensures robustness in mixed-signal systems where ground bounce may induce negative transients.
What is the thermal performance of the LTC6242HVIGN#PBF in SSOP-16 package?
The LTC6242HVIGN#PBF in GN (SSOP-16) package has a junction-to-ambient thermal resistance (θJA) of 135°C/W. At maximum rated supply (±5V) and full 4×1.9mA quiescent current (7.6mA total), power dissipation is ~76mW - resulting in ~10.3°C junction-to-ambient rise above ambient. This allows reliable operation up to +85°C ambient without forced airflow or heatsinking.
