Product details
Overview
TLV2784CPWG4 from Texas Instruments is a quad rail-to-rail input/output operational amplifier optimized for low-voltage, low-power precision signal conditioning. 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 9 nV/√Hz input voltage noise at 10 kHz - enabling high-resolution data acquisition in battery-powered sensor interfaces and portable medical devices.
For engineers reviewing the TLV2784CPWG4 datasheet, TLV2784CPWG4 pinout, TLV2784CPWG4 application, or TLV2784CPWG4 equivalent, key selection criteria include its 1.8 V minimum supply, −40°C to 125°C industrial temperature range, TSSOP-14 package footprint, shutdown capability per channel pair, and verified rail-to-rail output swing down to 180 mV from rails at 1.8 V.
Technical Context
The TLV2784CPWG4 implements a CMOS input stage with rail-to-rail common-mode input range (−0.2 V to VDD+0.2 V) and complementary output stage enabling full-supply-swing operation. Its 650 µA/channel quiescent current supports always-on sensing while maintaining 8 MHz bandwidth - a critical trade-off balance for high-speed, low-noise analog front-ends.
Each of the four amplifiers features independent shutdown control via shared 1/2SHDN (Pin 8) and 3/4SHDN (Pin 16), reducing supply current to ≤1.7 µA per channel in shutdown mode. The device uses internal compensation for unity-gain stability with 2 kΩ load and ≤25 pF capacitive load, with phase margin ≥58° under recommended conditions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2784IDR | Same die, SOIC-14 package; higher θJA (122.3°C/W) limits power handling in dense layouts | Lacks TSSOP thermal pad; unsuitable for thermally constrained PCBs with >200 mW total dissipation | Select TLV2784CPWG4 for space-constrained, thermally demanding designs requiring TSSOP-14 footprint |
| OPA2333PWR | Zero-drift architecture; 0.1 µV/°C offset drift vs TLV2784CPWG4's 8 µV/°C; 350 µA/channel vs 650 µA | Superior DC accuracy but lower 350 kHz GBW - not suitable for >100 kHz signal conditioning | Choose TLV2784CPWG4 when bandwidth >500 kHz and supply >1.8 V are required; choose OPA2333PWR for sub-µV DC stability at cost of speed |
Compared with TLV2784IDR, TLV2784CPWG4 offers 30% lower thermal resistance and 25% smaller board area; compared with OPA2333PWR, it provides >20× higher bandwidth at 1.8 V but trades off long-term DC drift performance for speed and low-voltage operation.

FAQ
What is the maximum capacitive load the TLV2784CPWG4 can drive without external compensation?
The TLV2784CPWG4 is unity-gain stable with ≤25 pF capacitive load and 2 kΩ resistive load. For loads exceeding 10 pF, TI recommends adding a series nulling resistor (RNULL) between the output and load to maintain ≥58° phase margin and prevent ringing - as validated in Figure 30 of the SLOS245E datasheet. This design constraint directly impacts PCB layout for ADC driver and filter applications.
Does the TLV2784CPWG4 support true rail-to-rail input at 1.8 V supply?
Yes, the TLV2784CPWG4 supports rail-to-rail input common-mode range from −0.2 V to VDD+0.2 V across its full 1.8 V to 3.6 V supply range. At 1.8 V, this means inputs operate from −0.2 V to +2.0 V - verified in Figure 1 and Figure 2 of the SLOS245E datasheet. This allows direct interfacing with sensors whose output exceeds the supply rail, such as piezoelectric elements.
How does the shutdown function work on the TLV2784CPWG4?
The TLV2784CPWG4 uses two dedicated shutdown pins: Pin 6 (1/2SHDN) disables Channels 1 and 2, and Pin 16 (3/4SHDN) disables Channels 3 and 4. Pulling either pin low reduces supply current per channel to ≤1.7 µA and places outputs in high-impedance state. Pins may be left floating to enable - but parasitic leakage must be managed to avoid unintended shutdown, per Section 15 of SLOS245E.
What is the guaranteed input offset voltage specification for TLV2784CPWG4 over temperature?
The TLV2784CPWG4 is a commercial-grade (C-suffix) device rated for 0°C to 70°C operation. Its input offset voltage is guaranteed ≤3000 µV over this full range, with a typical value of 250 µV at 25°C. The temperature coefficient is 8 µV/°C, meaning worst-case drift adds ≤560 µV across the 70°C span - confirmed in Table 1 of the SLOS245E electrical characteristics.
Can TLV2784CPWG4 operate from a split supply configuration?
Yes, the TLV2784CPWG4 supports split-supply operation from ±0.9 V to ±1.8 V, as specified in the Recommended Operating Conditions table (page 4 of SLOS245E). This allows use in bipolar signal chains where dual supplies are preferred - though its rail-to-rail input/output architecture delivers maximum benefit in single-supply systems like battery-powered equipment.
