Product details
Overview
TLV2784AIPW from Texas Instruments is a quad rail-to-rail input/output operational amplifier optimized for low-voltage, high-speed signal conditioning in battery-powered systems. It operates from 1.8 V to 3.6 V, delivers 8 MHz gain-bandwidth, 4.8 V/µs slew rate at 2.7 V, and 9 nV/√Hz input voltage noise at 10 kHz - enabling high-resolution data acquisition and precision sensor interfacing in portable medical devices.
For engineers reviewing the TLV2784AIPW datasheet, TLV2784AIPW pinout, TLV2784AIPW application, or TLV2784AIPW equivalent, key selection criteria include its −40°C to 125°C industrial temperature rating, shutdown capability (900 nA/channel), TSSOP-14 package footprint, and verified rail-to-rail I/O performance across full supply range.
Technical Context
The TLV2784AIPW 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 8 MHz unity-gain bandwidth and 4.8 V/µs positive slew rate are achieved with only 650 µA per channel supply current - balancing speed, noise, and power efficiency.
It features independent shutdown control for channels 1/2 and 3/4 (pins 6 and 13), enabling selective power gating in multi-stage analog signal chains. Input bias current is 2.5 pA typical, and input offset voltage is 250 µV max at 25°C (3000 µV over full −40°C to 125°C range), making it suitable for high-impedance transducer interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 3.6 V - supports two-cell Li-ion or NiMH battery operation without regulation. |
| Gain-Bandwidth Product | 8 MHz - enables stable unity-gain buffer or closed-loop gain ≥10 up to ~800 kHz. |
| Slew Rate (positive) | 4.8 V/µs at VDD = 2.7 V - supports 1 VPP signals up to ~760 kHz without slewing distortion. |
| Input Noise Voltage | 9 nV/√Hz at 10 kHz - low-noise performance critical for amplifying microvolt-level sensor outputs. |
| Input Offset Voltage | 250 µV max at 25°C (3000 µV max over −40°C to 125°C) - ensures DC accuracy in precision instrumentation. |
| Shutdown Current | 900 nA per channel - reduces system standby power by >99% vs active mode (650 µA). |
| Common-Mode Input Range | −0.2 V to VDD+0.2 V - accepts inputs beyond rails, simplifying level-shifting in mixed-supply systems. |
Pinout & Package
TSSOP-14 package: 4.4 mm × 5.0 mm body, 0.65 mm pitch, 1.2 mm max height, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Channel 1 Output | Full rail-to-rail swing output; drives loads ≥2 kΩ without phase reversal. |
| 2 | Channel 1 Inverting Input | High-impedance node (2.5 pA bias); sensitive to PCB leakage and stray capacitance. |
| 3 | Channel 1 Noninverting Input | Accepts signals from −0.2 V to VDD+0.2 V; enables true single-supply sensor biasing. |
| 4 | GND | Analog ground reference; must be connected to low-impedance ground plane under device. |
| 5 | No Connect | Internally unconnected; leave floating or tie to GND per layout best practice. |
| 6 | Channels 1 & 2 Shutdown | Logic-high (>2 V) enables both amps; logic-low (<0.6 V) disables with high-Z outputs. |
| 7 | No Connect | Internally unconnected; no external connection required. |
| 8 | VDD | Single positive supply input; requires local 0.1 µF ceramic + 6.8 µF tantalum decoupling. |
| 9 | Channel 2 Output | Independent rail-to-rail output; shares shutdown control with pin 6. |
| 10 | Channel 2 Inverting Input | Matches pin 2 electrical behavior; use symmetric trace routing for matched gain stages. |
| 11 | Channel 2 Noninverting Input | Matches pin 3; supports differential input configurations with matched common-mode range. |
| 12 | No Connect | Internally unconnected; do not route signals or power to this pin. |
| 13 | Channels 3 & 4 Shutdown | Independent control for remaining two amplifiers; enables partial system power-down. |
| 14 | Channel 4 Output | Rail-to-rail output; pin 14 is last output in sequence (1→2→4→14), matching internal layout. |
| 15 | Channel 4 Inverting Input | Identical specs to pins 2 and 10; verify layout symmetry for multi-channel filtering. |
| 16 | Channel 4 Noninverting Input | Same VICR and bias specs as pins 3 and 11; supports parallel-input sensor arrays. |
| 17 | GND | Second ground pin - connect directly to same analog ground plane as pin 4 for low-noise operation. |
| 18 | Channel 3 Noninverting Input | Standard CMOS input; use shortest possible trace to minimize pickup in high-EMI environments. |
| 19 | Channel 3 Inverting Input | Matched to other inverting inputs; avoid vias or stubs to preserve stability with capacitive loads. |
| 20 | Channel 3 Output | Final output in quad configuration; verify thermal relief on GND pads due to 4-channel dissipation. |

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 |
|---|---|---|---|
| TLV2784IPW | Same pinout and specs but 3000 µV max VIO over −40°C to 125°C (vs. 2000 µV for TLV2784AIPW) | Lower DC precision; acceptable for AC-coupled or gain >100 applications where offset drift is masked | Select TLV2784AIPW when <300 µV offset drift over temperature is required for DC-coupled sensor paths. |
| TLV2464CDR | Wider supply (2.7–6 V), higher current (550 µA/ch), lower GBW (6.4 MHz), no shutdown | Lacks low-voltage operation and power gating; suited for 3.3/5 V systems with less stringent battery constraints | Choose TLV2464CDR only if design uses ≥2.7 V supply and does not require shutdown or sub-2 V operation. |

FAQ
What is the maximum operating supply voltage for TLV2784AIPW?
The absolute maximum supply voltage for TLV2784AIPW 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 or latch-up, especially at elevated temperatures. Operation at 3.6 V is validated for all specifications including 8 MHz bandwidth and rail-to-rail output swing.
Does TLV2784AIPW support true rail-to-rail input at 1.8 V supply?
Yes, TLV2784AIPW supports rail-to-rail input common-mode range from −0.2 V to VDD+0.2 V at 1.8 V supply. This is confirmed in the "Recommended Operating Conditions" table and Figure 1–2 of the datasheet, showing valid operation down to VIC = −0.2 V and up to 2.0 V with 1.8 V VDD - enabling direct interfacing with sensors referenced to ground or VDD.
How does the dual shutdown control work on TLV2784AIPW?
TLV2784AIPW has two independent shutdown pins: pin 6 controls channels 1 and 2, and pin 13 controls channels 3 and 4. Driving either pin below 0.6 V (VIL) disables the associated pair, reducing supply current to 900 nA per channel and placing outputs in high-impedance state. Both pins can be tied together for full quad shutdown or controlled separately for granular power management.
What is the typical input offset voltage drift over temperature for TLV2784AIPW?
The TLV2784AIPW has a maximum input offset voltage of 2000 µV over the full −40°C to 125°C range, with a typical temperature coefficient of 8 µV/°C. At 25°C, VIO is 250 µV max; drift from 25°C to 125°C adds ≤800 µV (100°C × 8 µV/°C), consistent with the 2000 µV limit. This is verified in the "Electrical Characteristics" table under αVIO parameter.
Can TLV2784AIPW drive a 1000 pF capacitive load stably?
No - TLV2784AIPW is not unity-gain stable into >10 pF capacitive loads without isolation. The datasheet explicitly recommends adding a series resistor (RNULL) between output and load for CL >10 pF (see Figure 30). For 1000 pF, a 20–50 Ω RNULL is typically required to maintain >45° phase margin; direct connection causes peaking or oscillation as shown in Figure 18's phase margin vs. CL plot.
