Product details
Overview
LT6203HMS8#PBF from Analog Devices (formerly Linear Technology) is a dual, rail-to-rail input/output, ultralow-noise operational amplifier optimized for precision signal conditioning in wide-supply, low-power systems. It delivers 1.9nV/√Hz input voltage noise at 100kHz, 100MHz gain bandwidth, and 25V/µs slew rate while drawing only 2.5mA per amplifier at 5V - enabling high-fidelity analog front-ends in DSL receivers, battery-backed instrumentation, and A/D driver circuits.
For engineers reviewing the LT6203HMS8#PBF datasheet, LT6203HMS8#PBF pinout, LT6203HMS8#PBF application, or LT6203HMS8#PBF equivalent, key selection criteria include its –40°C to 125°C operating temperature range, MSOP-8 package with standard dual op amp pinout, rail-to-rail output swing within 210mV of rails at 15mA sink/source, and guaranteed 83MHz gain bandwidth at extended temperature.
Technical Context
The LT6203HMS8#PBF integrates two fully independent, unity-gain-stable amplifiers with matched input stages enabling precise differential signal processing. Its bipolar input architecture provides low input bias current (±7.4µA typ at VCM = half supply), while complementary NPN/PNP input pairs ensure rail-to-rail common-mode input range and low distortion (–80dBc THD at 1MHz).
Designed for low-voltage operation down to 2.5V total supply, it maintains 90dB typical CMRR and 74dB PSRR across ±1.25V to ±5V supplies, supporting robust performance in noisy industrial and telecom environments where supply rejection and common-mode immunity are critical for signal integrity.

Pinout & Package
LT6203HMS8#PBF is housed in an 8-lead plastic MSOP (MS8) package, 3mm × 3mm × 1.1mm profile, with exposed pad connected to V– for thermal enhancement. Pinout follows industry-standard dual op amp configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT A | Amplifier A output | Capable of sourcing/sinking ≥15mA while maintaining rail-to-rail swing; requires local 0.1µF bypass to V– |
| 2 - –IN A | Inverting input A | High-impedance node; layout symmetry critical for matching with +IN A in differential configurations |
| 3 - +IN A | Non-inverting input A | DC-coupled to reference or sensor; input capacitance 1.5pF limits high-Z source bandwidth |
| 4 - V– | Negative supply / GND | Power and thermal reference; exposed pad must be soldered to PCB ground plane for θJA = 250°C/W |
| 5 - V+ | Positive supply | Accepts 2.5V to 12.6V total supply; decoupling required within 5mm of pin |
| 6 - OUT B | Amplifier B output | Electrically isolated from OUT A; shares same supply rails but independent output stage |
| 7 - –IN B | Inverting input B | Matched to –IN A (0.3mV max offset match) for dual-channel instrumentation applications |
| 8 - +IN B | Non-inverting input B | Independent signal path; enables dual-channel filtering, buffering, or active gain control |

FAQ
What is the maximum operating temperature for the LT6203HMS8#PBF?
The LT6203HMS8#PBF is specified and guaranteed to operate from –40°C to +125°C ambient temperature. This H-grade qualification is explicitly confirmed in the Absolute Maximum Ratings table and Electrical Characteristics sections covering the –40°C to 125°C range, making it suitable for under-hood automotive and industrial control applications where thermal margins are critical. The LT6203HMS8#PBF junction temperature must not exceed 150°C.
Does the LT6203HMS8#PBF support single-supply operation?
Yes, the LT6203HMS8#PBF supports true single-supply operation from 2.5V to 12.6V total supply voltage. Its rail-to-rail input common-mode range includes both supply rails, and its output swings to within 210mV of V+ and V– at 15mA load - enabling direct interfacing with 3.3V or 5V microcontrollers and ADCs without level-shifting circuitry. The LT6203HMS8#PBF maintains specified performance across this full supply range.
What is the gain bandwidth product of the LT6203HMS8#PBF at elevated temperature?
At the full –40°C to +125°C operating range, the LT6203HMS8#PBF guarantees a minimum gain bandwidth product of 83MHz (tested at 1MHz). This value is explicitly listed in the Electrical Characteristics tables annotated with the "l" symbol denoting the –40°C to 125°C specification range. The typical GBW remains 100MHz at 25°C, but design margin must be based on the 83MHz min value for worst-case high-temperature operation. The LT6203HMS8#PBF retains unity-gain stability across this range.
Is the LT6203HMS8#PBF pin-compatible with other dual op amps in MSOP-8 packages?
Yes, the LT6203HMS8#PBF uses the industry-standard dual op amp pinout for MSOP-8: pins 1/6 = outputs, 2/7 = inverting inputs, 3/8 = non-inverting inputs, 4 = V–, 5 = V+. This matches pinouts of devices like the AD8628ARMZ and OPA2333AIDR, enabling drop-in replacement in many layouts - though electrical parameters (noise, bandwidth, supply current) differ significantly. Always verify layout compatibility and performance requirements before substitution. The LT6203HMS8#PBF pinout is confirmed in the Pin Configuration diagram for MS8 PACKAGE.
What is the typical input offset voltage drift of the LT6203HMS8#PBF?
The LT6203HMS8#PBF has a typical input offset voltage drift of 3.0µV/°C, with a maximum of 9.0µV/°C over the –40°C to +125°C range. This parameter is explicitly specified in the Electrical Characteristics tables under "VOS TC" with conditions VCM = half supply and the "l" notation for the extended temperature grade. This low drift supports stable DC gain accuracy in temperature-varying environments without frequent recalibration. The LT6203HMS8#PBF drift performance is consistent across its H-grade variants.
