Product details
Overview
LTC6088HGN#PBF from Analog Devices is a quad, rail-to-rail input/output, unity-gain stable CMOS operational amplifier optimized for high-impedance sensor signal conditioning. It delivers 14MHz gain bandwidth, 7.2V/µs slew rate, 1pA typical input bias current at 25°C, 0.75mV max offset voltage, and operates from 2.7V to 5.5V supply across –40°C to 125°C. It is deployed in portable medical instrumentation and precision shock/vibration sensor front-ends.
For engineers reviewing the LTC6088HGN#PBF datasheet, LTC6088HGN#PBF pinout, LTC6088HGN#PBF application, or LTC6088HGN#PBF equivalent, key selection criteria include guaranteed 125°C operation, rail-to-rail I/O swing within 30mV of rails, low 1.05mA per amplifier supply current, shutdown mode with 2.3µA per amp quiescent draw, and compatibility with high-impedance transducer interfaces requiring sub-picoampere bias stability.
Technical Context
The LTC6088HGN#PBF employs complementary PMOS/NMOS input pairs to achieve rail-to-rail common-mode input range (V– to V+), enabling full-supply utilization in single-ended sensor interfaces. Its output stage uses class AB architecture to deliver ±45mA short-circuit current while maintaining low quiescent power.
It integrates independent active-low shutdown pins per amplifier pair (SHDNA/SHDNB) only in DFN variants; the GN package omits these pins and relies on global power control. The device is specified with 70dB min CMRR and 93dB min PSRR over 2.7V–5.5V supply, supporting precision DC-coupled measurement paths in noisy industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 14MHz - supports stable closed-loop operation up to 10kHz with ≥100dB open-loop gain margin for anti-aliasing filter design. |
| Input Bias Current | 1pA (typ @ 25°C) - enables direct interfacing with >10GΩ source impedances (e.g., pH probes, piezoelectric sensors) without significant DC error. |
| Offset Voltage | ±750µV (max @ –40°C to 125°C) - ensures ≤0.75mV baseline error in uncalibrated 12-bit data acquisition systems. |
| Slew Rate | 7.2V/µs - allows full-scale 2Vpp output transitions in <280ns, suitable for 10kHz sinusoidal signals with <0.1% distortion. |
| Supply Voltage Range | 2.7V to 5.5V - compatible with Li-ion battery (3.0–4.2V) and USB-powered (5V) portable equipment without LDO regulation. |
| Operating Temperature | –40°C to 125°C (H-grade) - qualified for under-hood automotive sensor modules and industrial motor drive feedback circuits. |
| Channel Separation | –120dB @ 10kHz - prevents crosstalk between adjacent amplifiers in multi-channel ECG or vibration analysis systems. |
Pinout & Package
Package: 16-lead plastic SSOP (narrow, 0.150-inch width), JEDEC MO-153 compliant. Exposed pad not present; all leads are gull-wing surface-mount. Pin 1 marked by notch/dimple; lead coplanarity ≤0.102mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUTA) | Amplifier A output | Capable of sourcing/sinking ≥25mA; swings to within 30mV of V+ or V– under no-load conditions. |
| 2 (–INA) | Inverting input of Amp A | Rail-to-rail common-mode range; differential input capacitance = 2.7pF (diff), 4.2pF (common). |
| 3 (+INA) | Noninverting input of Amp A | Same rail-to-rail CM range as –INA; matched to –INA for <5µV/°C offset drift. |
| 4 (V+) | Positive supply rail | Accepts 2.7V–5.5V; PSRR ≥93dB ensures immunity to digital supply noise coupling. |
| 5 (+INB) | Noninverting input of Amp B | Electrically isolated from +INA; channel separation ≥–120dB prevents inter-amplifier interference. |
| 6 (–INB) | Inverting input of Amp B | Independent high-impedance node; requires guard ring layout for pA-level bias current integrity. |
| 7 (OUTB) | Amplifier B output | Identical drive capability and rail-swing performance to OUTA; supports independent load termination. |
| 8 (NC) | No connect | Not internally bonded; must remain unconnected and unstubbed to avoid parasitic coupling. |
| 9 (OUTD) | Amplifier D output | Full-output-stage performance identical to OUTA/OUTB; enables 4-channel synchronous sampling. |
| 10 (–IND) | Inverting input of Amp D | Matched offset and drift characteristics to other inputs; validated for 125°C operation. |
| 11 (+IND) | Noninverting input of Amp D | Supports common-mode voltages from V– to V+; critical for single-supply bridge amplifier topologies. |
| 12 (V–) | Negative supply rail | Reference for all inputs/outputs; internal ESD diodes clamp to V– if inputs exceed V– by >0.3V. |
| 13 (+INC) | Noninverting input of Amp C | Enables simultaneous 4-channel signal conditioning with <0.1% gain mismatch across temperature. |
| 14 (–INC) | Inverting input of Amp C | Low-noise node (12nV/√Hz); optimized for use with 10kΩ feedback networks to minimize resistor noise dominance. |
| 15 (OUTC) | Amplifier C output | Delivers same 7.2V/µs slew rate and 14MHz GBW as other channels; supports parallel output summing. |
| 16 (NC) | No connect | Unused pad; must be left floating-no thermal or electrical function. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC6078HGN#PBF | Lower supply current (60µA/amp), lower GBW (1.5MHz), higher VOS (25µV max), same 125°C rating and SSOP-16 package. | Better suited for always-on battery sensors where bandwidth <100kHz suffices; unsuitable for 10kHz vibration sensing. | Select LTC6078HGN#PBF when ultra-low power dominates over speed; verify loop stability with reduced GBW. |
| LTC6242HGN#PBF | Higher GBW (18MHz), lower noise (7nV/√Hz), higher supply current (1.5mA/amp), same 125°C rating and SSOP-16 package. | Preferred for wideband audio or high-speed data acquisition where noise floor is critical and power budget allows. | Select LTC6242HGN#PBF when 7nV/√Hz noise and 18MHz GBW justify +0.45mA/amp overhead; confirm layout supports higher slew-induced layout sensitivity. |
Compared with LTC6078HGN#PBF, the LTC6088HGN#PBF trades 1.5MHz bandwidth and 60µA quiescent current for 14MHz GBW and 1.05mA draw-enabling faster settling in sensor digitization. Against LTC6242HGN#PBF, it sacrifices 7nV/√Hz noise and 18MHz GBW to achieve 1pA bias current and lower power, prioritizing high-Z source fidelity over raw speed.

FAQ
What is the maximum operating junction temperature for LTC6088HGN#PBF?
The LTC6088HGN#PBF has a maximum junction temperature (TJMAX) of 150°C, with thermal resistance θJA = 110°C/W in the GN16 SSOP package. This allows reliable operation at ambient temperatures up to 125°C when PCB copper area and airflow meet standard JEDEC 51-7 guidelines.
Does LTC6088HGN#PBF support true rail-to-rail input common-mode range?
Yes, the LTC6088HGN#PBF supports rail-to-rail input common-mode voltage from V– to V+, achieved via dual PMOS/NMOS input pairs. This is confirmed in the datasheet Section "Rail-to-Rail Input" and validated across –40°C to 125°C for the H-grade variant.
Can LTC6088HGN#PBF drive capacitive loads without instability?
The LTC6088HGN#PBF can drive up to 100pF capacitive load in unity-gain configuration, as verified in Typical Performance Characteristic Figure G21. For larger loads, adding a 10Ω–50Ω series resistor between output and load restores phase margin, per Application Information Section "Capacitive Load".
What is the guaranteed input offset voltage specification for LTC6088HGN#PBF over temperature?
The LTC6088HGN#PBF guarantees ±750µV maximum input offset voltage across the full –40°C to 125°C operating temperature range, as specified in the Electrical Characteristics table under "H SUFFIX" column for LTC6088GN devices.
Is LTC6088HGN#PBF pin-compatible with other packages in the LTC6087/LTC6088 family?
No-LTC6088HGN#PBF (16-pin SSOP) is not pin-compatible with LTC6088HDHC#PBF (16-pin DFN) due to differing pin functions: the DFN includes SHDN pins and exposed V– pad, while the SSOP has NC pins and no shutdown capability. Board redesign is required for package substitution.
