Product details
Overview
TLV2785IPWR 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, delivers 8 MHz gain-bandwidth, 4.8 V/µs slew rate at 2.7 V, and draws only 650 µA per channel - enabling high-speed data acquisition in battery-powered sensor interfaces and portable instrumentation.
For engineers reviewing the TLV2785IPWR datasheet, TLV2785IPWR pinout, TLV2785IPWR application, or TLV2785IPWR equivalent, this page provides verified specifications, TSSOP-16 package terminal mapping, industrial-grade (−40°C to 125°C) performance data, shutdown functionality details, and validated alternative op-amps for low-voltage rail-to-rail designs.
Technical Context
The TLV2785IPWR integrates four independent amplifiers with complementary-input MOSFET front-end architecture, supporting rail-to-rail common-mode input voltage (−0.2 V to VDD+0.2 V) and rail-to-rail output swing. Its 8 MHz unity-gain bandwidth and 9 nV/√Hz input noise at 10 kHz are achieved with only 650 µA/channel supply current - a key enabler for high-resolution SAR ADC driver stages.
Each channel includes an active-low shutdown control (pins 7 and 15), reducing quiescent current to 900 nA/channel when asserted. The device uses internal biasing that maintains stable phase margin (>58°) into 25 pF loads, and supports operation down to 1.8 V single supply - compatible with two-cell Li-ion or NiMH battery systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 3.6 V - enables direct interface with 2-cell rechargeable batteries (±0.9 V to ±1.8 V split supply) |
| Gain-Bandwidth Product | 8 MHz - supports stable unity-gain buffer configurations up to ~1 MHz with 10 pF load |
| Slew Rate | 4.8 V/µs at VDD = 2.7 V - sufficient for 12-bit DAC output settling in <1 µs with AV = 1 |
| Input Offset Voltage | 3000 µV max (I-suffix, full range) - suitable for medium-precision sensor amplification without trimming |
| Supply Current per Channel | 650 µA typical - allows four-channel operation under 2.6 mA total, critical for always-on IoT nodes |
| Input Noise Voltage | 9 nV/√Hz at 10 kHz - low enough for audio preamp and high-SNR transducer signal chains |
| Operating Temperature | −40°C to 125°C - qualified for automotive cabin and industrial motor-control environments |
Pinout & Package
TSSOP-16 (PW) package: 4.4 mm × 5.0 mm body, 0.65 mm pitch, thin-profile surface-mount. Moisture sensitivity level (MSL) 2a per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |

| 2, 4, 6, 11 | IN− | Inverting input of channels 1–4; matched to IN+ for common-mode rejection |
| 7, 15 | 1/2SHDN, 3/4SHDN | Active-low shutdown controls - pull ≤0.6 V to disable corresponding pair of amplifiers |
| 8 | GND | Analog ground reference; must be connected to low-impedance PCB ground plane |
| 9 | VDD | Positive supply rail (1.8–3.6 V); requires local 0.1 µF ceramic + 6.8 µF tantalum decoupling |
| 10, 13, 14, 16 | OUT1–OUT4 | Rail-to-rail output terminals; drive ≥10 mA into resistive loads, high-Z in shutdown |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2784IPW | Quad op-amp, identical pinout and specs, but lacks shutdown function on any channel | No power-gating capability - unsuitable for duty-cycled sensing where standby current matters | Select when cost sensitivity outweighs shutdown requirement and layout space permits discrete enable logic |
| OPA2333AIPW | Zero-drift dual op-amp (not quad); 12 µV max VIO vs. TLV2785IPWR's 3000 µV; higher 350 µA/channel current | Better DC accuracy for precision weigh scales, but no shutdown and only two channels per package | Choose when offset drift <0.05 µV/°C is mandatory and system can accommodate separate dual-amplifier placement |
Compared with TLV2784IPW, TLV2785IPWR adds per-pair shutdown for >700× lower standby current; compared with OPA2333AIPW, it trades ultra-low offset for quad integration and lower quiescent power - making TLV2785IPWR optimal for multi-sensor, battery-constrained industrial monitoring.

FAQ
What is the maximum recommended supply voltage for TLV2785IPWR?
The absolute maximum supply voltage for TLV2785IPWR 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 shift and accelerated aging; operation at 3.6 V is fully characterized for all specifications including 8 MHz bandwidth and rail-to-rail output swing.
Does TLV2785IPWR support true rail-to-rail input at 1.8 V supply?
Yes - TLV2785IPWR guarantees rail-to-rail input common-mode range from −0.2 V to VDD+0.2 V across its full operating temperature range. At 1.8 V supply, this means inputs function correctly from −0.2 V to 2.0 V, enabling direct interface with sensors referenced to ground or VDD without level-shifting circuitry.
How does the shutdown function work on TLV2785IPWR?
TLV2785IPWR has two dedicated shutdown pins: pin 7 (1/2SHDN) disables channels 1 and 2; pin 15 (3/4SHDN) disables channels 3 and 4. Driving either pin ≤0.6 V places the corresponding amplifiers in high-impedance output state and reduces their supply current to 900 nA/channel. Leaving pins floating or pulling them ≥2 V enables normal operation.
Can TLV2785IPWR drive a 10 kΩ load while maintaining rail-to-rail output?
Yes - TLV2785IPWR delivers rail-to-rail output swing into 10 kΩ loads across the full temperature range. At VDD = 1.8 V and TA = 25°C, VOH ≥1.77 V and VOL ≤155 mV at 1 mA load, meaning it achieves >98% of full-scale swing into 10 kΩ (0.18 mA load). Performance is confirmed in Figure 4 and Figure 5 of the datasheet.
Is TLV2785IPWR suitable for driving SAR ADC inputs?
Yes - TLV2785IPWR is well-suited for driving 12- to 14-bit SAR ADCs. Its 8 MHz GBW, 4.8 V/µs slew rate, and 9 nV/√Hz noise ensure fast settling (<1 µs to 0.01%) and minimal code-dependent distortion. The quad configuration allows simultaneous buffering of multiple ADC channels, and shutdown capability minimizes power between conversions.
