Product details
Overview
LTC6087HMS8#TRPBF from Analog Devices (formerly Linear Technology) is a dual, 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 LTC6087HMS8#TRPBF datasheet, LTC6087HMS8#TRPBF pinout, LTC6087HMS8#TRPBF application, or LTC6087HMS8#TRPBF equivalent, this page provides verified package mapping (8-lead MSOP), thermal-rated performance (–40°C to 125°C), shutdown functionality (2.3µA per amp), rail-to-rail I/O swing (within 30mV of rails), and validated alternative op-amps for low-bias, low-noise signal chains.
Technical Context
The LTC6087HMS8#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 maintaining 30mV rail headroom under no-load conditions.
It integrates active shutdown control (SHDN pins not present in MS8 package), achieves 70dB minimum CMRR and 93dB minimum PSRR over 2.7V–5.5V supply, and sustains unity-gain stability driving up to 100pF capacitive loads - all specified across –40°C to 125°C for automotive and industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 14MHz - supports stable closed-loop operation up to ~1MHz at G = 10 without phase margin degradation. |
| 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 - ensures ≤0.75mV DC error in 1V full-scale measurement systems without trimming. |
| Slew Rate | 7.2V/µs - allows clean 10kHz sine wave reproduction at 2VPP output swing. |
| Supply Voltage Range | 2.7V to 5.5V - compatible with single-cell Li-ion (3.0–4.2V) and 3.3V/5V logic domains. |
| Operating Temperature | –40°C to 125°C - qualified for under-hood automotive and industrial control applications. |
| Shutdown Current | 2.3µA per amplifier - reduces system standby power by >99% vs active mode (1.05mA). |
Pinout & Package
Package: 8-lead MSOP (MS8), 3mm × 3mm body, exposed pad connected to V–, RoHS-compliant, tape-and-reel (TRPBF).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | +IN A | Noninverting input of Amplifier A - accepts signals from V– to V+ with <5µV/°C drift. |
| 2 | –IN A | Inverting input of Amplifier A - used for feedback networks; matched to +IN A for CMRR optimization. |
| 3 | OUT A | Amplifier A output - swings within 30mV of V+ or V– under no load; drives ≥10kΩ loads. |
| 4 | V– | Negative supply rail - also connected to exposed thermal pad; must be soldered to PCB ground plane. |
| 5 | V+ | Positive supply rail - decoupling capacitor (0.1µF) required close to pin for stability. |
| 6 | –IN B | Inverting input of Amplifier B - electrically isolated from Amplifier A; channel separation >120dB @ 10kHz. |
| 7 | +IN B | Noninverting input of Amplifier B - identical DC specs and noise performance as Amplifier A inputs. |
| 8 | OUT B | Amplifier B output - independent output stage; no internal shutdown control in MS8 package. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input & output | Input common-mode range spans V– to V+; output swings to within 30mV of either rail - maximizes dynamic range in low-voltage systems. |
| Ultra-low input bias current | 1pA typical at 25°C - preserves signal integrity in high-Z transducer interfaces (e.g., Murata PKGS-00MX1 shock sensors). |
| Low 1/f noise | 2.5µVP-P (0.1Hz–10Hz) - critical for DC-stable amplification in medical ECG front-ends and precision weigh scales. |
| High PSRR & CMRR | 93dB PSRR / 70dB CMRR min - rejects supply ripple and common-mode interference in noisy industrial environments. |
| Unity-gain stable | Phase margin ≥45° with 5pF load - eliminates need for external compensation in gain-of-1 buffer or follower configurations. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC6078IMS8#PBF | Lower supply current (60µA/amp), lower GBW (1.5MHz), higher VOS drift (0.7µV/°C max) | Better suited for always-on battery monitoring; insufficient bandwidth for 10kHz vibration sensing | Select when micropower (<100µA) dominates over speed/noise requirements |
| LTC6241IMS8#PBF | Lower noise (7nV/√Hz), higher GBW (18MHz), higher input bias (0.2pA typ), no shutdown | Superior for wideband audio or fast data acquisition; lacks low-power shutdown mode | Select when 0.2pA bias and 7nV/√Hz noise justify absence of shutdown and higher quiescent current |
Compared with LTC6087HMS8#TRPBF, LTC6078IMS8#PBF trades bandwidth and noise for 17× lower supply current, while LTC6241IMS8#PBF improves noise and speed but removes shutdown capability - making LTC6087HMS8#TRPBF the balanced choice for battery-powered precision sensing with intermittent operation.

FAQ
What is the maximum operating temperature for LTC6087HMS8#TRPBF?
The LTC6087HMS8#TRPBF is rated for continuous operation from –40°C to 125°C, with guaranteed electrical performance across this full range. Its junction temperature limit is 150°C, and thermal resistance θJA is 200°C/W in the MS8 package - requiring appropriate PCB copper area for high-power dissipation scenarios.
Does LTC6087HMS8#TRPBF support shutdown mode?
No, the LTC6087HMS8#TRPBF does not include shutdown pins. Shutdown functionality (SHDNA/SHDNB) is only available in the 10-lead DFN (DD) package variant (e.g., LTC6087HDD#TRPBF). The MS8 package omits these pins, so LTC6087HMS8#TRPBF operates continuously when powered.
What is the input common-mode voltage range of LTC6087HMS8#TRPBF?
The LTC6087HMS8#TRPBF features true rail-to-rail input operation, with common-mode voltage range specified from V– to V+ across the full –40°C to 125°C temperature range. This is achieved via dual PMOS/NMOS input stages that auto-switch based on input voltage level relative to the supplies.
Can LTC6087HMS8#TRPBF drive capacitive loads?
Yes, the LTC6087HMS8#TRPBF is unity-gain stable and can directly drive up to 100pF capacitive loads. For larger capacitances, adding a small series resistor (e.g., 10Ω–50Ω) between the output and load restores phase margin - a technique validated in the datasheet's Typical Performance Characteristics (Figure G21/G22).
Is LTC6087HMS8#TRPBF pin-compatible with other LTC6087 variants?
The LTC6087HMS8#TRPBF shares identical pinout and function with the LTC6087CMS8#TRPBF (commercial grade), differing only in temperature rating (–40°C to 125°C vs. –40°C to 85°C). It is not pin-compatible with the 10-lead DFN variant (LTC6087HDD#TRPBF), which adds SHDNA/SHDNB pins at positions 5 and 6.
