Product details
Overview
TLV2771CD from Texas Instruments is a single-channel CMOS rail-to-rail output operational amplifier optimized for low-voltage, low-power precision signal conditioning. It delivers 10.5 V/µs slew rate, 5.1 MHz gain-bandwidth product, 360 µV input offset voltage, and 1 mA supply current per channel across 2.5 V to 5.5 V operation - enabling high-fidelity analog front-ends in portable medical sensors and battery-powered data acquisition systems.
For engineers reviewing the TLV2771CD datasheet, TLV2771CD pinout, TLV2771CD application, or TLV2771CD equivalent, key selection considerations include its SOT-23-5 package footprint, micropower shutdown mode (<1 µA), −40°C to 125°C industrial temperature range, and verified rail-to-rail output swing into 600-Ω loads with 0.005% THD+N at 1 kHz.
Technical Context
The TLV2771CD employs a CMOS input stage with 2 pA input bias current and 17 nV/√Hz input noise voltage, supporting high-impedance sensor interfacing without significant DC error or noise degradation. Its unity-gain-stable architecture achieves 46° phase margin with 600-Ω load and 100-pF capacitive load, ensuring robust stability in ADC reference buffering and active filter designs.
It features micropower shutdown control (SHDN pin) that reduces supply current to <1 µA while maintaining fast turnon/turnoff times (2.4 µs / 444 ns), making it suitable for duty-cycled measurement systems where power gating is critical for battery life extension.

Equivalent & Alternatives
The following parts are listed as comparable options for similar op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA333AIDBVR | Zero-drift architecture; 0.1 µV/°C offset drift vs. TLV2771CD's 2 µV/°C; higher 350 nA input bias current | Better long-term DC stability in precision weight scales; less suitable for high-Z pH or piezoelectric sensors | Select OPA333AIDBVR when sub-µV offset drift dominates over power or speed requirements |
| MCP6001T-E/OT | Lower 1 MHz GBW and 0.6 V/µs slew rate; 100 µA supply current; no shutdown pin | Targeted at ultra-low-power sensor interfaces where bandwidth <100 kHz suffices | Select MCP6001T-E/OT for cost-sensitive, low-speed applications where shutdown functionality is unnecessary |
Compared with OPA333AIDBVR and MCP6001T-E/OT, the TLV2771CD uniquely balances 5.1 MHz bandwidth, 10.5 V/µs slew rate, rail-to-rail output, and micropower shutdown in a 5-pin SOT-23 - making it the only option among the three qualified for high-speed, low-power, temperature-robust signal conditioning in space-constrained industrial and automotive designs.

FAQ
What is the maximum supply voltage rating for TLV2771CD?
The absolute maximum supply voltage for TLV2771CD 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. At 5 V, TLV2771CD achieves its full 10.5 V/µs slew rate and 5.1 MHz gain-bandwidth product, while maintaining rail-to-rail output swing and 0.005% THD+N performance.
Does TLV2771CD support rail-to-rail input operation?
No, TLV2771CD does not support rail-to-rail input operation. Its common-mode input voltage range is specified from GND to VDD − 1.3 V at 25°C. For example, with a 3.3-V supply, the valid input range is 0 V to 2.0 V. This limitation necessitates proper biasing of AC-coupled or high-side sensor signals - but the rail-to-rail output remains fully functional across the entire supply range.
How does the shutdown feature of TLV2771CD function electrically?
The TLV2771CD's shutdown pin (pin 5 in SOT-23-5) is active-high: driving it to >2.0 V (relative to GND) disables the amplifier and reduces supply current to <1 µA. During shutdown, the output enters high-impedance state, and input bias currents drop below 100 pA. Turnon time is 2.4 µs to 50% of final output, allowing rapid wake-up in event-driven sensing architectures without external reset sequencing.
Can TLV2771CD drive a 600-Ω load while maintaining low THD+N?
Yes, TLV2771CD is explicitly characterized for 0.005% THD+N at 1 kHz while driving a 600-Ω load, per the official TI datasheet (SLOS209G, page 9). This performance is achieved with AV = 1, VO(PP) = 2 V, and VDD = 5 V. The combination of high slew rate (10.5 V/µs), low output impedance (~20 Ω), and rail-to-rail swing enables clean signal delivery to legacy telecom line receivers and audio CODECs without external buffering.
Is TLV2771CD qualified for automotive applications?
TLV2771CD carries the 'C' temperature suffix (0°C to 70°C), indicating commercial-grade qualification. While it shares the same silicon die as automotive-qualified variants like TLV2771ID (−40°C to 125°C), TLV2771CD itself is not AEC-Q100 qualified. For automotive use, designers must select TLV2771ID or TLV2771AID - both of which undergo additional stress testing and lot traceability per automotive standards. TLV2771CD remains suitable for non-safety-critical consumer and industrial applications.
