Product details
Overview
TLV2784IPW from Texas Instruments is a quad rail-to-rail input/output operational amplifier optimized for low-voltage, low-power applications. It operates from 1.8 V to 3.6 V supply, delivers 8 MHz gain-bandwidth, 4.8 V/µs slew rate at 2.7 V, and consumes only 650 µA per channel - enabling high-speed signal conditioning in battery-powered data converters and portable instrumentation.
For engineers reviewing the TLV2784IPW datasheet, TLV2784IPW pinout, TLV2784IPW application, or TLV2784IPW equivalent, key selection criteria include its −40°C to 125°C industrial temperature range, TSSOP-14 package with integrated shutdown control per amplifier pair, rail-to-rail output swing down to 180 mV from rails at 1.8 V, and 9 nV/√Hz input voltage noise at 10 kHz.
Technical Context
The TLV2784IPW implements a CMOS input stage with rail-to-rail common-mode input range (−0.2 V to VDD+0.2 V) and rail-to-rail output swing, supporting single-supply operation down to 1.8 V. Its internal architecture enables stable unity-gain operation with 58° phase margin into 2 kΩ//25 pF loads.
Each of the four amplifiers features independent shutdown capability via shared 1/2SHDN (Pin 8) and 3/4SHDN (Pin 16) terminals, reducing supply current to ≤1.7 µA per channel in shutdown mode while placing outputs in high-impedance state - critical for power-gated sensor front-ends and multiplexed analog signal chains.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2784CDR | Same electrical specs, SOIC-14 package (8.65 mm × 3.9 mm), commercial temp (0°C to 70°C), no shutdown pins | Lacks shutdown control and industrial temperature rating - unsuitable for battery-gated or under-hood applications | Select when board space allows larger SOIC and operating environment stays within 0–70°C |
| OPA2333AIPW | Zero-drift architecture, 0.02 µV/°C drift, 6 µV max VIO, 350 µA/channel, 350 kHz GBW, no shutdown | Superior DC precision but lower speed - ideal for weigh scales and precision RTD interfaces, not high-speed data converters | Choose for µV-level offset stability over temperature; avoid when >1 MHz signal bandwidth required |
Compared with TLV2784CDR, the TLV2784IPW adds industrial temperature support and dual-pair shutdown - critical for automotive and portable equipment. Versus OPA2333AIPW, it trades DC precision for 23× higher bandwidth and integrated power gating, making it optimal for mixed-signal data acquisition where speed and power efficiency dominate.

FAQ
What is the maximum recommended supply voltage for TLV2784IPW?
The absolute maximum supply voltage for TLV2784IPW is 4 V, but the recommended operating range is strictly 1.8 V to 3.6 V per the datasheet. Exceeding 3.6 V risks parametric degradation and reduced reliability; operation at 3.6 V delivers optimal slew rate (≥4 V/µs) and output drive capability while maintaining 650 µA/channel supply current. Always use 0.1 µF ceramic + 6.8 µF tantalum decoupling on VDD.
Does TLV2784IPW support true rail-to-rail input and output simultaneously?
Yes, TLV2784IPW supports rail-to-rail input (VICR = −0.2 V to VDD+0.2 V) and rail-to-rail output (VOH ≥ VDD−180 mV, VOL ≤ 180 mV at 1.8 V) simultaneously across its full operating range. This enables direct interfacing with 1.8 V logic and full utilization of ADC reference voltages without level-shifting circuitry - verified at 1.8 V, 2.7 V, and 3.6 V supplies with load currents up to ±5 mA.
How does the shutdown function operate on TLV2784IPW?
TLV2784IPW uses two dedicated shutdown pins: Pin 8 (1/2SHDN) disables Amplifiers 1 and 2, and Pin 16 (3/4SHDN) disables Amplifiers 3 and 4. Driving either pin to GND reduces supply current per associated channel to ≤1700 nA and places outputs in high-impedance state. Leaving pins floating or tying them to VDD enables operation. Turnon/turnoff times are 800 ns and 200 ns respectively - fast enough for dynamic power gating in time-division multiplexed sensor arrays.
What is the typical input offset voltage and its drift over temperature for TLV2784IPW?
TLV2784IPW has a maximum input offset voltage of 3000 µV over the full −40°C to 125°C range, with a typical value of 250 µV at 25°C. Its temperature coefficient is 8 µV/°C maximum, meaning offset can drift up to ±1.2 mV across the full industrial temperature span. This level of drift is acceptable for AC-coupled or digitally calibrated systems like portable oscilloscopes and ultrasonic flow meters, but not for high-precision DC measurements without trimming.
Can TLV2784IPW drive capacitive loads without instability?
TLV2784IPW is stable for capacitive loads ≤10 pF with unity-gain configuration. For loads >10 pF (e.g., ADC input capacitance or long PCB traces), a series resistor (RNULL) must be added between amplifier output and load - typically 10–100 Ω depending on CL - to restore phase margin above 58°. The datasheet Figure 30 and application note SLOS245E Section "Driving a Capacitive Load" provide exact compensation guidelines validated up to 100 pF with RNULL = 47 Ω.
