Product details
Overview
LT1367CS#TRPBF from Analog Devices (formerly Linear Technology) is a quad precision rail-to-rail input and output operational amplifier in a 14-lead SOIC package. It operates from 1.8V single supply to ±15V dual supply, delivers 375µA per amplifier supply current, maintains 90dB CMRR over full rail-to-rail input range, and drives 30mA loads - enabling high-accuracy signal conditioning in low-voltage industrial sensor interfaces.
For engineers reviewing the LT1367CS#TRPBF datasheet, LT1367CS#TRPBF pinout, LT1367CS#TRPBF application, or LT1367CS#TRPBF equivalent, this page provides verified pin functions, rail-to-rail I/O performance data, quad-channel timing-critical use cases, and validated alternative op amps for precision analog front-ends requiring stable offset, wide supply range, and capacitive-load stability up to 1000pF.
Technical Context
The LT1367CS#TRPBF uses dual-input-stage architecture with PNP and NPN differential pairs that auto-switch across the full rail-to-rail common-mode range (VEE to VCC), eliminating input clamps and enabling true input operation at both supply rails. Its complementary Darlington output stage achieves rail-to-rail swing with <120mV low-side saturation and VCC–0.18V high-side swing at 2.5mA load.
It features conventional internal compensation optimized for stability with capacitive loads ≤1000pF - distinct from the LT1369's 0.1µF external capacitor requirement - and delivers 400kHz gain-bandwidth product with 0.13V/µs slew rate under unity-gain conditions at ±15V supplies.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad precision rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT1369CS#TRPBF | Requires 0.1µF output capacitor for stability; offers higher PSRR (105dB) and lower HF output impedance due to capacitor filtering | Better suited for mixed-signal systems with switching supplies or ADC drivers needing ultra-low noise floor | Select LT1369CS#TRPBF only if external capacitor placement is feasible and PSRR >100dB at 50kHz is required |
| AD8604ARUZ | FEMTOamp input bias (1pA typ), lower VOS (60µV max), but narrower supply range (2.7V–5.5V) and no rail-to-rail input at VCC | Ideal for ultra-low-power, high-impedance pH or photodiode sensors - not suitable for 12V or ±15V systems | Choose AD8604ARUZ for battery-powered micro-power designs with high-Z sources; avoid for wide-supply or true rail-to-rail input needs |
Compared with LT1369CS#TRPBF, LT1367CS#TRPBF avoids mandatory external capacitance and supports wider supply ranges, while AD8604ARUZ trades supply flexibility for femtoamp bias and microvolt offset - making LT1367CS#TRPBF the optimal balance of rail-to-rail fidelity, supply versatility, and capacitive-load simplicity in industrial analog signal chains.

FAQ
What is the maximum capacitive load the LT1367CS#TRPBF can drive without oscillation?
The LT1367CS#TRPBF is internally compensated for stable operation with capacitive loads up to 1000pF, as confirmed in its Electrical Characteristics table and Typical Performance Characteristics (TPC22). This eliminates need for external compensation networks in most filter, cable-driving, or ADC-buffer applications - unlike the LT1369CS#TRPBF which requires a 0.1µF capacitor. Exceeding 1000pF may degrade phase margin and cause peaking or ringing.
Does the LT1367CS#TRPBF support true rail-to-rail input operation at the positive supply rail (VCC)?
Yes, the LT1367CS#TRPBF supports true rail-to-rail input common-mode range including VCC, enabled by its dual-input-stage architecture with auto-switching between PNP and NPN differential pairs. Per the Applications Information section and Figure 1 schematic, the NPN stage activates within ~1.3V of VCC, allowing valid operation with inputs at VCC - a key differentiator from conventional op amps that require ≥1.5V headroom.
What is the guaranteed input offset voltage specification for LT1367CS#TRPBF over its full operating temperature range?
The LT1367CS#TRPBF guarantees a maximum input offset voltage of 950µV over the 0°C to 70°C temperature range, as specified in the "Electrical Characteristics" table under "l" (temperature-limited) conditions at VS = 5V, 0V. At 25°C only, the limit is 800µV. This parameter reflects worst-case matching between channels and process variation - critical for multi-amplifier configurations like instrumentation amps.
Can the LT1367CS#TRPBF operate from a single 1.8V supply?
Yes, the LT1367CS#TRPBF is explicitly characterized and specified for operation from 1.8V single supply (V+ = 1.8V, V– = 0V), as stated in the "Description" section and confirmed in Electrical Characteristics tables tested at VS = 3V, 0V and VS = 1.8V equivalents. Its rail-to-rail input/output architecture remains functional at this minimum supply, though GBW reduces to ~160kHz and output swing compresses slightly - verified in TPC25 and TPC27 curves.
How does the LT1367CS#TRPBF achieve high common-mode rejection ratio (CMRR) across the full input range?
The LT1367CS#TRPBF achieves ≥77dB CMRR over the full rail-to-rail input range through matched PNP and NPN input stage design, lateral bipolar transistor fabrication on Linear's proprietary process, and on-die trimming of both stages' offset voltages. As detailed in the Applications Information section, the dual-stage architecture ensures consistent transconductance and bias point tracking across VEE to VCC - preventing the CMRR collapse seen in single-stage op amps near supply rails.
