Product details
Overview
LMV774MT/NOPB from Texas Instruments is a quad, rail-to-rail output, low-noise precision operational amplifier optimized for 2.7V–5.5V single-supply operation. It delivers 3.5MHz gain-bandwidth product, 7.5nV/√Hz input voltage noise at 10kHz, 550µA per amplifier supply current, and 850µV max input offset voltage (LMV771-specified limit extended to LMV774 per family datasheet), enabling high-accuracy signal conditioning in portable instrumentation and automotive sensor interfaces.
For engineers reviewing the LMV774MT/NOPB datasheet, LMV774MT/NOPB pinout, LMV774MT/NOPB application, or LMV774MT/NOPB equivalent, key selection criteria include guaranteed RRO swing into 2kΩ loads (50mV from rail), −40°C to 125°C operating range, 100dB open-loop gain, and TSSOP-14 packaging - all critical for battery-powered data acquisition, transducer amplification, and precision current sensing where low power, wide temperature tolerance, and DC accuracy are mandatory.
Technical Context
The LMV774MT/NOPB implements a CMOS-input, rail-to-rail output op-amp architecture with input common-mode range extending to V− and up to V+ − 0.9V. Its internal compensation ensures stable unity-gain operation with capacitive loads up to 100pF while maintaining 79° phase margin at 5V supply.
It supports dual- and quad-amplifier configurations within the same family, with identical AC/DC specifications across LMV772/LMV774 variants except for channel count and package. The LMV774MT/NOPB is explicitly characterized for 2.7V and 5V operation, with guaranteed performance over −40°C to 125°C when driving ≥2kΩ loads.

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2333PWR | Zero-drift architecture; 0.02µV/°C drift vs. LMV774MT/NOPB's −0.35µV/°C; higher 350nA supply current per amp | Better long-term DC stability in temperature-varying environments; less suitable for ultra-low-power battery operation | Select OPA2333PWR when microvolt-level drift over temperature is critical and power budget allows ≥350µA/amp |
| MCP6004-E/ST | Higher 1.6mV max VOS; lower 1MHz GBW; 100µA supply current; rated only to 125°C with reduced output drive | Adequate for cost-sensitive consumer applications but lacks LMV774MT/NOPB's noise and precision for instrumentation-grade designs | Select MCP6004-E/ST only for non-critical signal paths where 1mV offset and 1MHz bandwidth are acceptable |
Compared with OPA2333PWR and MCP6004-E/ST, LMV774MT/NOPB offers the optimal balance of low noise (7.5nV/√Hz), moderate power (550µA), and guaranteed 3.5MHz bandwidth across −40°C to 125°C - making it uniquely suited for battery-powered precision measurement where zero-drift isn't required but low-frequency noise and rail-to-rail swing are essential.

FAQ
What is the maximum operating temperature range for LMV774MT/NOPB?
The LMV774MT/NOPB is fully specified and guaranteed to operate from −40°C to +125°C. This extended temperature range is validated per the datasheet's Operating Ratings table and applies to all DC and AC parameters when driving ≥2kΩ loads. At temperatures above 85°C with loads <2kΩ, output swing and gain may degrade per the datasheet's footnotes.
Does LMV774MT/NOPB support true rail-to-rail input?
No, LMV774MT/NOPB does not support rail-to-rail input. Its input common-mode voltage range is specified as 0V to V+ − 0.9V. While it accepts signals down to ground (V−), it cannot accommodate inputs within 0.9V of the positive rail. This limitation is inherent to its CMOS-input stage design and is documented in the Electrical Characteristics tables.
What is the typical supply current consumption of LMV774MT/NOPB per amplifier?
The typical supply current for LMV774MT/NOPB is 550µA per amplifier at 2.7V supply and 25°C. This value increases slightly with supply voltage and temperature, reaching up to 960µA per amplifier at 5V and 125°C. Total quiescent current for all four amplifiers is therefore 2.2mA typical at 2.7V, making it suitable for low-power portable designs.
Can LMV774MT/NOPB drive a 600Ω load while maintaining rail-to-rail output swing?
Yes, LMV774MT/NOPB can drive a 600Ω load, but with reduced swing: output is guaranteed to swing within 100mV of each rail (not 50mV) under those conditions. The 50mV specification applies only to 2kΩ loads. Driving 600Ω loads increases output stage current demand, causing greater voltage drop across internal output transistors - a trade-off explicitly quantified in the datasheet's VO parameter tables.
Is LMV774MT/NOPB pin-compatible with other devices in the LMV77x family?
LMV774MT/NOPB is not pin-compatible with LMV771 (SC70-5) or LMV772 (MSOP-8/SOIC-8) due to differing channel counts and packages. However, within the quad variant, LMV774MT/NOPB (TSSOP-14) shares identical pinout and functionality with LMV774IDR (SOIC-14) and LMV774IPWPR (TSSOP-14 with different tape/reel coding). No PCB redesign is needed when substituting between these three part numbers.
