Product details
Overview
TLV2774CPW from Texas Instruments is a quad CMOS operational amplifier optimized for single-supply, rail-to-rail output operation across 2.5 V to 5.5 V. It delivers 10.5 V/µs slew rate, 5.1 MHz gain-bandwidth product, 360 µV input offset voltage, and 1 mA per-channel supply current-enabling high-fidelity signal conditioning in portable data acquisition and automotive sensor interfaces.
For engineers reviewing the TLV2774CPW datasheet, TLV2774CPW pinout, TLV2774CPW application, or TLV2774CPW equivalent, key selection criteria include its rail-to-rail output swing into 600-Ω loads (0.005% THD+N), micropower shutdown mode (<1 µA/channel), and guaranteed operation from −40°C to 125°C in TSSOP-14 packaging.
Technical Context
The TLV2774CPW employs a CMOS input stage with 2 pA input bias current and 17 nV/√Hz input noise voltage, supporting precision DC-coupled measurement paths. Its unity-gain-stable architecture achieves 46° phase margin with 600-Ω load and 100-pF capacitive load, enabling direct driving of ADC reference inputs without external isolation.
It integrates independent channel enable/disable control via shared 1/2SHDN and 3/4SHDN pins, allowing selective power gating of amplifier pairs. The device is characterized at both 2.7 V and 5 V supplies, with input common-mode range extending to within 1.3 V of VDD and rail-to-rail output swing delivering >2.4 V high-level and <0.21 V low-level output under 2.2-mA load.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail output op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2474IPW | Lower slew rate (1.5 V/µs), higher supply current (600 µA/channel), I/O rail-to-rail, wider offset (2.5 mV max) | Better DC precision but insufficient bandwidth for >100-kHz sensor signal conditioning | Select when ultra-low input bias (0.5 pA) and rail-to-rail input are required over speed |
| OPA4340UA | Higher precision (125 µV offset), lower noise (11 nV/√Hz), higher cost, SO-14 only (no TSSOP) | Superior for medical-grade biosignal amplification where offset drift dominates error budget | Choose when sub-200 µV offset and <1 ppm/°C drift are mandatory, and board space permits SOIC |
Compared with TLV2774CPW, TLV2474IPW trades bandwidth and output drive for lower input bias and rail-to-rail input capability, while OPA4340UA provides superior DC accuracy and noise at the expense of speed and package flexibility-making TLV2774CPW optimal for cost-sensitive, high-speed, single-supply industrial and automotive signal chains.

FAQ
What is the maximum operating supply voltage for TLV2774CPW?
The absolute maximum supply voltage for TLV2774CPW is 7 V, but the recommended operating range is 2.5 V to 5.5 V. Operation above 5.5 V risks permanent damage and violates the device's specified electrical characteristics; TI characterizes performance only within the 2.5–5.5 V range, with optimal AC performance at 5 V (10.5 V/µs slew rate, 5.1 MHz GBW).
Does TLV2774CPW support true rail-to-rail input?
No, TLV2774CPW features rail-to-rail *output* only. Its input common-mode voltage range extends from GND to VDD − 1.3 V (e.g., 0 V to 3.7 V at VDD = 5 V), meaning it cannot accept signals at the positive rail. This limitation is explicitly defined in the "Recommended Operating Conditions" table of the SLOS209G datasheet and must be accounted for in front-end design.
How does the shutdown function work on TLV2774CPW?
TLV2774CPW has two independent shutdown pins: Pin 8 (1/2SHDN) disables amplifiers A and B, while Pin 16 (3/4SHDN) disables amplifiers C and D. Driving either pin low reduces the respective pair's supply current to <1.5 µA (typ). Both pins must be high to enable all four channels; no internal pull-up resistors are present, so external logic or microcontroller GPIO must control them.
Can TLV2774CPW drive a 100-pF capacitive load stably?
Yes, TLV2774CPW is unity-gain stable with 100-pF capacitive loads, as confirmed by phase margin (46°) and gain margin (12 dB) measurements in the datasheet's operating characteristics tables. However, layout best practices-including short traces, local 0.1-µF ceramic decoupling at VDD, and avoiding long unterminated output runs-are essential to prevent peaking or oscillation in production designs.
Is TLV2774CPW qualified for automotive applications?
TLV2774CPW is rated for operation from −40°C to +125°C and is listed in TI's Q-Temp automotive qualification program, meeting AEC-Q100 stress test requirements. While the CPW suffix denotes commercial temperature grade (0°C to 70°C), the underlying die and process are automotive-capable; for production automotive use, specify TLV2774IPW (I-suffix) or TLV2774QPW (Q-suffix) instead.
