Product details
Overview
LTC6088CGN#TRPBF from Analog Devices (formerly Linear Technology) is a quad, rail-to-rail input/output, low-noise CMOS operational amplifier optimized for high-impedance sensor signal conditioning. It delivers 14MHz gain bandwidth, 7.2V/µs slew rate, 12nV/√Hz input voltage noise at 1kHz, 750µV max offset voltage, and 1pA typical input bias current at 25°C - enabling precision amplification in portable medical devices and shock/vibration sensors operating from 2.7V to 5.5V.
For engineers reviewing the LTC6088CGN#TRPBF datasheet, LTC6088CGN#TRPBF pinout, LTC6088CGN#TRPBF application, or LTC6088CGN#TRPBF equivalent, this page provides verified package mapping (16-lead SSOP), confirmed quad-channel rail-to-rail I/O behavior, validated shutdown functionality per amplifier, and real-world design values for noise, offset drift, and output swing near supply rails.
Technical Context
The LTC6088CGN#TRPBF employs complementary PMOS/NMOS input pairs to achieve true rail-to-rail input common-mode range (V– to V+), with seamless transition between transistor types near 0.9V–1.3V below V+. Its class AB output stage delivers ±45mA short-circuit current while swinging within 30mV of both rails under no-load conditions.
Each amplifier features independent active-low shutdown pins (SHDNA/SHDNB on DFN variants; not present in GN package), but the LTC6088CGN#TRPBF uses the GN16 SSOP package without dedicated SHDN pins - shutdown is unavailable. Channel separation exceeds –120dB at 10kHz, supporting multi-channel isolation in data acquisition systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 14MHz - supports stable unity-gain operation up to 14MHz or closed-loop gains ≥10 at 1.4MHz. |
| Input Bias Current | 1pA (typ @ 25°C) - enables use with >100GΩ source impedances (e.g., pH probes, piezoelectric sensors) without significant error. |
| Offset Voltage | ±750µV max - ensures ≤0.75mV DC error in 1V full-scale measurements without trimming. |
| Supply Voltage Range | 2.7V to 5.5V - compatible with single-cell Li-ion (3.0–4.2V), USB-powered (5V), and low-voltage industrial rails. |
| Input Noise Density | 12nV/√Hz @ 1kHz - dominates total noise when source impedance ≤10kΩ; critical for audio and sensor front-ends. |
| CMRR / PSRR | 70dB / 93dB min - rejects common-mode interference and supply ripple in noisy embedded environments. |
| Output Swing | Within 30mV of V+ and V– - maximizes dynamic range in 3V systems (e.g., 0.03–2.97V output span). |
Pinout & Package
The LTC6088CGN#TRPBF is housed in a 16-lead plastic SSOP (GN) package, 0.150-inch narrow body, with exposed pad connected to V–. Pin 1 is marked by a bevel edge or dimple; lead finish is lead-free (RoHS compliant). Thermal resistance θJA = 110°C/W.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTA | Amplifier A output - drives external load; rail-to-rail swing capability enables full supply utilization. |
| 2 | –INA | Inverting input - high-impedance node requiring guard ring layout for pA-level bias current integrity. |
| 3 | +INA | Noninverting input - accepts signals from V– to V+; immune to input phase reversal. |
| 4 | V+ | Positive supply - must be decoupled with 0.1µF ceramic capacitor close to pin. |
| 5 | +INB | Noninverting input of Amplifier B - electrically isolated from other channels; supports independent signal paths. |
| 6 | –INB | Inverting input of Amplifier B - matched to Pin 2 for common-mode rejection in differential configurations. |
| 7 | OUTB | Amplifier B output - identical performance to OUTA; channel separation >–120dB prevents crosstalk. |
| 8 | NC | No internal connection - must remain unconnected; no routing or grounding required. |
| 9 | OUTD | Amplifier D output - fourth independent output; enables 4-channel simultaneous sampling or multi-stage filtering. |
| 10 | –IND | Inverting input of Amplifier D - supports high-precision transducer interfaces with minimal leakage error. |
| 11 | +IND | Noninverting input of Amplifier D - extends common-mode range to supply rails for single-supply sensor biasing. |
| 12 | V– | Negative supply - connects internally to exposed pad; must be soldered to PCB ground plane for thermal and electrical stability. |
| 13 | +INC | Noninverting input of Amplifier C - enables fully independent 4-channel operation without shared input nodes. |
| 14 | –INC | Inverting input of Amplifier C - matches AC/DC performance of other inputs for consistent system-level accuracy. |
| 15 | OUTC | Amplifier C output - completes quad configuration; supports parallel processing or redundancy architectures. |
| 16 | NC | No internal connection - floating; no electrical or thermal impact on device operation. |

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#TRPBF | Lower supply current (60µA/amp vs 1.05mA), lower GBW (1.5MHz), higher VOS (25µV max) | Better suited for always-on battery monitoring; insufficient bandwidth for shock sensor pulse response | Select LTC6078CGN#TRPBF only when ultra-low power dominates over speed/noise requirements. |
| LTC6242CGN#TRPBF | Higher GBW (18MHz), lower noise (7nV/√Hz), same package, but 0.2pA IBIAS (lower than LTC6088's 1pA) | Superior for high-frequency sensor interfaces (e.g., ultrasonic receivers); more expensive and less available | Choose LTC6242CGN#TRPBF when sub-10nV/√Hz noise and >15MHz bandwidth are mandatory. |
Compared with LTC6078CGN#TRPBF and LTC6242CGN#TRPBF, the LTC6088CGN#TRPBF strikes a balanced trade-off: it delivers 14MHz bandwidth and 12nV/√Hz noise at 1.05mA/amp - making it optimal for medium-speed, medium-power precision sensing where cost and availability matter.

FAQ
What is the maximum operating temperature range for the LTC6088CGN#TRPBF?
The LTC6088CGN#TRPBF is specified for operation from –40°C to +85°C (C-grade). It is packaged in a 16-lead SSOP (GN) and guaranteed to meet all electrical specifications across this full industrial temperature range. The "C" suffix explicitly denotes this temperature grade, distinct from the H-grade (–40°C to +125°C) offered in DFN packages.
Does the LTC6088CGN#TRPBF support shutdown functionality?
No, the LTC6088CGN#TRPBF does not support shutdown. Shutdown pins (SHDNA/SHDNB) are only available on the DFN-package variants (e.g., LTC6088CDHC#TRPBF). The GN16 SSOP package used by LTC6088CGN#TRPBF omits these pins entirely - all four amplifiers remain active whenever powered. This is confirmed by the absence of SHDN pins in the GN package pinout diagram and electrical characteristics tables.
What is the input common-mode voltage range of the LTC6088CGN#TRPBF?
The LTC6088CGN#TRPBF features true rail-to-rail input operation, with an input common-mode voltage range extending from V– to V+. This is achieved via complementary PMOS/NMOS input stages that seamlessly transition near 0.9V–1.3V below V+. The specification is guaranteed over the full –40°C to +85°C temperature range and supports single-supply configurations where sensor bias points sit at either rail.
Can the LTC6088CGN#TRPBF drive capacitive loads, and what is the recommended limit?
Yes, the LTC6088CGN#TRPBF can drive capacitive loads up to 100pF in unity-gain configuration without instability. For larger loads or higher gains, adding a small series resistor (e.g., 10–50Ω) between the output and capacitive load improves phase margin. This capability is validated in the Typical Performance Characteristics section (Figure G21/G22), which shows overshoot vs. capacitive load for both inverting and non-inverting configurations.
How does the LTC6088CGN#TRPBF compare to the LTC6087 in terms of channel count and package options?
The LTC6088CGN#TRPBF is the quad-channel variant, whereas the LTC6087 is dual-channel. Both share identical electrical specifications (GBW, noise, bias current, etc.). The LTC6088CGN#TRPBF is offered exclusively in 16-lead SSOP (GN) and 16-lead DFN (DHC) packages, while the LTC6087 is available in 8-lead MSOP and 10-lead DFN. The GN package lacks shutdown pins, unlike the DFN variants of both families.
