Product details
Overview
LTC6088CGN#PBF from Analog Devices is a quad, rail-to-rail input/output, unity-gain stable CMOS operational amplifier with 14MHz gain bandwidth, 7.2V/µs slew rate, and 1pA typical input bias current at 25°C. It operates from 2.7V to 5.5V supply, delivers ±750µV max offset voltage, and is specified for –40°C to 85°C industrial temperature range - ideal for high-impedance transducer signal conditioning in portable medical sensors.
For engineers reviewing the LTC6088CGN#PBF datasheet, LTC6088CGN#PBF pinout, LTC6088CGN#PBF application, or LTC6088CGN#PBF equivalent, key selection criteria include verified rail-to-rail I/O swing (within 30mV of rails), low 10nV/√Hz input noise density at 1kHz, shutdown current ≤2.3µA per amplifier, and compatibility with 16-lead SSOP layout constraints.
Technical Context
The LTC6088CGN#PBF integrates dual PMOS/NMOS input stages to achieve full rail-to-rail common-mode input range (V– to V+), enabling direct interfacing with sensors operating near supply rails. Its class AB output stage supports 25mA short-circuit current while maintaining 30mV output swing headroom under no-load conditions.
Internal ESD protection diodes on all pins define the input bias current behavior, which rises with temperature (15pA typ. at 85°C) and common-mode voltage - critical for pH probe and photodiode applications where board leakage must be mitigated via guard rings.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 14MHz - supports stable closed-loop operation up to 10kHz with ≥10x phase margin at AV = 1, RL = 10kΩ, CL = 5pF. |
| Input Bias Current | 1pA (typ, 25°C) - enables use with >1GΩ source impedances without significant DC error, e.g., piezoelectric shock sensors. |
| Offset Voltage | ±750µV (max, C-grade) - ensures ≤0.75mV DC error in 1V full-scale instrumentation amplifiers without trimming. |
| Supply Voltage Range | 2.7V to 5.5V - compatible with single-cell Li-ion (3.0–4.2V) and 3.3V logic systems without level-shifting. |
| Output Swing | Within 30mV of V+ and V– (no load) - maximizes dynamic range in low-voltage data acquisition systems. |
| Channel Separation | –120dB at 10kHz - prevents crosstalk between adjacent channels in quad-sensor front-ends. |
| Shutdown Current | 2.3µA per amplifier - reduces system standby power by >99% vs active mode (1.05mA), enabling duty-cycled sensor nodes. |
Pinout & Package
The LTC6088CGN#PBF is housed in a 16-lead plastic SSOP (GN) package with 0.025" pitch, 0.150" body width, and exposed pad connected to V–. Pin 1 is marked by notch or dimple; exposed pad must be soldered to PCB ground plane for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUTA, OUTB, OUTC, OUTD | Amplifier output terminals | Class AB outputs swing within 30mV of rails; high-impedance in shutdown mode. |
| –INA, –INB, –INC, –IND | Inverting inputs | Accept full rail-to-rail common-mode voltage; require guard ring routing for <1pA leakage. |
| +INA, +INB, +INC, +IND | Noninverting inputs | Same rail-to-rail range as inverting inputs; matched to –IN pins for CMRR >70dB. |
| V+, V– | Power supply pins | V+ accepts 2.7–5.5V; V– is reference/ground; exposed pad internally tied to V–. |
| NC (Pins 8, 15) | No-connect terminals | Not bonded; must remain unconnected and unstubbed to avoid parasitic coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables direct interface with 0–5V sensors and ADCs without level-shifting circuitry. |
| 1pA input bias current (25°C) | Supports ultra-high-impedance sources like pH electrodes and piezoelectric accelerometers. |
| 14MHz GBW with unity-gain stability | Allows stable 10kHz signal conditioning without external compensation components. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC6078CGN#PBF | Lower supply current (60µA/amp), lower GBW (1.5MHz), same 1pA IB and rail-to-rail I/O. | Better suited for always-on ultra-low-power sensor nodes; insufficient bandwidth for >10kHz audio or vibration sensing. | Select when power budget <100µA/channel dominates over bandwidth requirements. |
| LTC6242IGN#PBF | Higher GBW (18MHz), lower noise (7nV/√Hz), but higher IB (0.2pA typ) and no shutdown mode. | Preferred for high-fidelity audio or fast data acquisition where shutdown is unnecessary. | Select when lowest noise and highest speed are critical, and continuous operation is acceptable. |
Compared with LTC6088CGN#PBF, LTC6078CGN#PBF trades bandwidth for micropower operation, while LTC6242IGN#PBF offers superior noise and speed but lacks shutdown capability - making LTC6088CGN#PBF optimal for battery-powered, multi-channel, duty-cycled precision sensing.

FAQ
What is the maximum operating temperature range for the LTC6088CGN#PBF?
The LTC6088CGN#PBF is rated for –40°C to 85°C operation, with guaranteed performance across this industrial temperature range. Its absolute maximum junction temperature is 150°C, and thermal resistance θJA is 110°C/W in the GN16 SSOP package - requiring appropriate PCB copper area for sustained 1.05mA per amplifier dissipation.
Does the LTC6088CGN#PBF support rail-to-rail input and output simultaneously?
Yes, the LTC6088CGN#PBF supports true rail-to-rail input (V– to V+) and output (within 30mV of V+ and V– under no load). This allows direct interfacing with sensors and ADCs operating at the supply rails, eliminating level-shifting components in single-supply 3.3V or 5V systems.
How does the shutdown feature work on the LTC6088CGN#PBF?
The LTC6088CGN#PBF does not include dedicated SHDN pins - those are only present in the DFN packages (LTC6088CDHC#PBF). The GN16 SSOP variant has no shutdown functionality; all four amplifiers operate continuously when powered. For shutdown capability, select the DFN-packaged LTC6088CDHC#PBF instead.
What layout practices minimize input bias current errors in high-impedance applications using the LTC6088CGN#PBF?
To preserve the LTC6088CGN#PBF's 1pA input bias current, implement guard rings around all input traces, connect them to a low-impedance node at the same potential (e.g., output in unity-gain buffer), remove solder mask over guard rings, and avoid routing high-voltage traces near inputs. Use clean, flux-free assembly to prevent leakage paths through the SSOP package body.
Is the LTC6088CGN#PBF unity-gain stable, and what capacitive load can it drive?
Yes, the LTC6088CGN#PBF is unity-gain stable. It can drive up to 100pF capacitive load in unity-gain configuration without oscillation. For larger loads, add a small series resistor (e.g., 10Ω–50Ω) between output and load to isolate capacitance and maintain phase margin above 45°.
