Product details
Overview
LTC6088HDHC#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, 12nV/√Hz input voltage noise at 1kHz, ±750µV max offset voltage (H-grade), 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 LTC6088HDHC#PBF datasheet, LTC6088HDHC#PBF pinout, LTC6088HDHC#PBF application, or LTC6088HDHC#PBF equivalent, key selection criteria include its H-grade (–40°C to 125°C) temperature rating, DFN-16 (5mm × 3mm) package with exposed V– pad, shutdown capability per amplifier, and verified performance in low-power, low-noise, high-common-mode-range analog front-ends.
Technical Context
The LTC6088HDHC#PBF employs complementary PMOS/NMOS input stages to achieve rail-to-rail common-mode input range (V– to V+), with seamless transition between pairs near 0.9V–1.3V below V+. Its class AB output stage delivers rail-to-rail swing within 30mV of supply rails under no-load conditions and sustains ≥25mA sink/source short-circuit current.
Each amplifier features independent active-low shutdown pins (SHDNA–SHDND), enabling selective power gating in multi-channel systems. The device maintains unity-gain stability while driving ≥100pF capacitive loads in unity gain, with phase margin ≥45° at 10kΩ//5pF load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 14MHz - supports closed-loop bandwidth up to ~10MHz in gain-of-10 configurations for fast sensor signal acquisition. |
| Input Bias Current | 1pA (typ @ 25°C) - enables use with >1GΩ source impedances (e.g., pH probes, piezoelectric sensors) without significant DC error. |
| Offset Voltage | ±750µV max (H-grade) - ensures ≤0.75mV initial DC error in precision instrumentation amplifiers and transducer interfaces. |
| Supply Voltage Range | 2.7V to 5.5V - compatible with single-cell Li-ion, 3.3V logic, and dual-supply industrial systems without level-shifting. |
| Shutdown Current | 2.3µA per amp - reduces total system quiescent power to <10µA when three amplifiers are disabled in quad configuration. |
| CMRR / PSRR | 70dB / 93dB min - rejects common-mode noise from noisy digital supplies and maintains accuracy in mixed-signal PCB environments. |
| Slew Rate | 7.2V/µs - supports clean amplification of 10kHz full-scale sine waves with <0.1% distortion at 2VPP output. |
Pinout & Package
The LTC6088HDHC#PBF is housed in a 16-lead plastic DFN package (5mm × 3mm) with an exposed thermal pad connected internally to V–. The package requires soldering the exposed pad to a PCB ground plane for optimal thermal performance (θJA = 43°C/W) and EMI suppression.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | OUTA, –INA, +INA, V+ | Amplifier A output, inverting input, noninverting input, positive supply - standard op-amp topology with rail-to-rail I/O. |
| 5, 6, 7, 8 | +INB, –INB, OUTB, SHDNB | Amplifier B inputs/outputs plus dedicated active-low shutdown - enables independent control of channel B. |
| 9, 10, 11, 12 | V–, +INC, –INC, OUTC | Negative supply reference and Amplifier C I/O - V– serves as return path for all four amplifiers and exposed pad. |
| 13, 14, 15, 16 | SHDNA, OUTD, –IND, +IND | Amplifier D shutdown and I/O - SHDNA allows per-amplifier power gating; all SHDN pins float to V+ if unconnected. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode range | Operates with inputs from V– to V+, eliminating level-shifting needs in single-supply systems with wide dynamic input signals. |
| 1pA input bias current (25°C) | Minimizes voltage error across high-impedance sources (e.g., 100MΩ strain gauge bridges), preserving measurement fidelity. |
| Independent per-amplifier shutdown | Reduces system power by disabling unused channels - critical for battery-powered data loggers with intermittent sensor polling. |
| 70dB minimum CMRR (–40°C to 125°C) | Maintains accuracy in automotive and industrial environments where supply ripple and ground bounce exceed 100mV peak-to-peak. |
| 12nV/√Hz input voltage noise (1kHz) | Enables detection of µV-level signals from low-output transducers (e.g., Murata PKGS-00MX1 shock sensors) without excessive gain-stage noise penalty. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC6078HDD#PBF | Lower supply current (600µA/amp vs 1.05mA), lower GBW (1.5MHz), higher VOS drift (0.7µV/°C vs 5µV/°C) | Better suited for micropower (<10µA) battery life extension; less suitable for >10kHz signal bandwidths | Select when ultra-low quiescent power dominates over speed/noise requirements. |
| LTC6242HDD#PBF | Higher GBW (18MHz), lower noise (7nV/√Hz), higher input bias current (0.2pA typ), same H-grade temp range | Superior for high-speed, low-noise applications like photodiode TIAs; less ideal for ultra-high-Z DC-coupled sensors | Select when 18MHz bandwidth and 7nV/√Hz noise justify trade-off in input bias current sensitivity. |
Compared with LTC6078HDD#PBF and LTC6242HDD#PBF, the LTC6088HDHC#PBF uniquely balances 14MHz bandwidth, 1pA input bias, and H-grade temperature operation - making it optimal for precision, wide-bandwidth sensor interfaces where both speed and ultra-high input impedance are required simultaneously.

FAQ
What is the maximum operating temperature range for the LTC6088HDHC#PBF?
The LTC6088HDHC#PBF is rated for continuous operation from –40°C to +125°C (H-grade), with guaranteed electrical performance across this full range per the datasheet's "H SUFFIX" specifications. This makes it suitable for under-hood automotive, industrial motor control, and downhole equipment applications where ambient temperatures exceed 85°C.
Does the LTC6088HDHC#PBF require external components for stability with capacitive loads?
The LTC6088HDHC#PBF drives up to 100pF capacitive loads in unity-gain configuration without external compensation. For loads exceeding 100pF, a small series resistor (e.g., 10Ω–50Ω) between the output and load improves phase margin and reduces overshoot - as validated in Figure 60878 G21/G22 of the datasheet.
How does the shutdown function work on the LTC6088HDHC#PBF?
Each amplifier in the LTC6088HDHC#PBF has a dedicated active-low shutdown pin (SHDNA–SHDND). Driving any SHDN pin ≤1.2V places its corresponding amplifier into high-impedance output state with ≤2.3µA supply current. Pins float to V+ via internal current sources when unconnected, enabling normal operation without pull-up resistors.
Can the LTC6088HDHC#PBF be used with a single 3.3V supply?
Yes - the LTC6088HDHC#PBF operates from 2.7V to 5.5V, making it fully compatible with standard 3.3V logic supplies. Its rail-to-rail input (V– to V+) and output (within 30mV of rails) ensure maximum signal swing and dynamic range in single-supply 3.3V systems, such as battery-powered IoT sensor nodes.
What is the purpose of the exposed pad on the LTC6088HDHC#PBF DFN package?
The exposed pad on the LTC6088HDHC#PBF is electrically connected to V– and must be soldered to a PCB copper pour tied to the system's negative supply or ground plane. This provides critical thermal dissipation (reducing θJA from 110°C/W to 43°C/W) and lowers inductance for improved PSRR and high-frequency stability.
