Product details
Overview
TLV2765IPW from Texas Instruments is a quad-channel, 1.8 V micropower rail-to-rail input/output operational amplifier with individual shutdown control per channel, specified for −40°C to 85°C industrial operation, 20 μA per channel supply current, 500 kHz unity-gain bandwidth, and 10 nA per-channel shutdown current - used in ultra-low-power sensor signal conditioning and battery-powered instrumentation.
For engineers reviewing the TLV2765IPW datasheet, TLV2765IPW pinout, TLV2765IPW application, or TLV2765IPW equivalent, key selection criteria include its 1.8–3.6 V single-supply range, rail-to-rail I/O swing at sub-2-V operation, 550 μV input offset voltage, 0.20 V/μs slew rate, and TSSOP-16 package with dedicated SHDN pins for each amplifier pair.
Technical Context
The TLV2765IPW implements CMOS input-stage architecture enabling rail-to-rail common-mode input range (−0.2 V to VDD + 0.2 V) and rail-to-rail output swing within 10–20 mV of supply rails at 100–500 μA load. Its micropower design uses optimized biasing to maintain 500 kHz gain-bandwidth product across 1.8–3.6 V while limiting quiescent current to 20 μA per channel.
Each of the four amplifiers features independent enable/disable via dedicated SHDN pins (pins 5 and 10), with turn-on time of 5 μs and turn-off time of 0.8 μs. Shutdown mode reduces supply current to 10 nA per channel, making it suitable for duty-cycled measurement systems where active time is brief and standby duration dominates battery life.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 3.6 V - supports two AA/AAA cells (end-of-life 1.8 V) or NiMH/NiCd (nominal 2.4 V) |
| Supply Current (per channel) | 20 μA typical at 1.8 V - enables multi-year battery life in low-duty-cycle sensor nodes |
| Shutdown Current (per channel) | 10 nA typical - reduces total system standby power to nanoampere level |
| Unity-Gain Bandwidth | 500 kHz - sufficient for DC–200 Hz sensor signals with margin for anti-alias filtering |
| Input Offset Voltage | 550 μV max at 25°C - enables accurate amplification of mV-level transducer outputs |
| Slew Rate | 0.20 V/μs - supports 100-kHz full-scale step response with <1% distortion |
| Input Common-Mode Range | −0.2 V to VDD + 0.2 V - accepts ground-referenced inputs even at 1.8 V supply |
| Output Swing (RL = 300 kΩ) | Within 20 mV of rails - preserves dynamic range in low-voltage ADC interfaces |
Pinout & Package
TSSOP-16 package (PW suffix), 5.0 mm × 4.4 mm body, 0.65 mm pitch, exposed thermal pad (not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplifier 1 output - rail-to-rail capable, drives high-impedance loads up to 300 kΩ |
| 2 | 1IN− | Inverting input of Amp 1 - CMOS input, 3 pA bias current, supports megaohm feedback networks |
| 3 | 1IN+ | Non-inverting input of Amp 1 - same rail-to-rail common-mode range as 1IN− |
| 4 | GND | Analog ground reference - must be low-impedance connection shared with decoupling capacitors |
| 5 | 1/2SHDN | Shutdown control for Amps 1 & 2 - logic high (≥2 V) enables both; logic low disables with 10 nA channel current |
| 6 | VDD | Positive supply - accepts 1.8–3.6 V; requires local 0.1 μF ceramic + 6.8 μF tantalum decoupling |
| 7 | 2OUT | Amplifier 2 output - independently buffered, identical specs to 1OUT |
| 8 | 2IN− | Inverting input of Amp 2 - electrically isolated from Amp 1 inputs |
| 9 | 2IN+ | Non-inverting input of Amp 2 - supports separate sensor or reference connections |
| 10 | 2SHDN | Shutdown control for Amps 3 & 4 - independent timing and logic threshold from Pin 5 |
| 11 | 3OUT | Amplifier 3 output - fully matched performance to Amps 1 & 2 |
| 12 | 3IN− | Inverting input of Amp 3 - no internal connection to other channels |
| 13 | 3IN+ | Non-inverting input of Amp 3 - usable for differential or single-ended configurations |
| 14 | GND | Second analog ground pin - improves PSRR and reduces crosstalk between channels |
| 15 | 4OUT | Amplifier 4 output - completes quad configuration with independent output drive |
| 16 | 4IN− | Inverting input of Amp 4 - supports 4-channel signal conditioning on single IC |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad micropower rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2454IPW | Higher supply current (23 μA/ch), no shutdown, wider supply range (2.7–6 V), 0.11 V/μs slew rate | Lacks per-channel shutdown; unsuitable for ultra-low-power duty-cycled systems | Select when higher bandwidth (650 kHz) and no shutdown requirement exist; not drop-in due to missing SHDN pins |
| LP324DR | Lower supply current (45 μA total for quad), no rail-to-rail output, 3 V minimum supply, no shutdown | Cannot operate below 3 V; output swing limited to ~1.2 V from rails at 3.3 V - insufficient for 1.8 V systems | Consider only for non-battery, 3.3 V+ designs where cost is primary; incompatible pinout and functionality |
Compared with TLV2765IPW, TLV2454IPW offers higher bandwidth but lacks shutdown and rail-to-rail input at 1.8 V, while LP324DR fails to meet the core 1.8 V rail-to-rail requirement - making TLV2765IPW uniquely suited for sub-2-V micropower sensing.

FAQ
What is the maximum supply voltage rating for TLV2765IPW?
The absolute maximum supply voltage for TLV2765IPW is 4 V. Operation above 3.6 V is not recommended, as the device is characterized and specified only up to 3.6 V. Exceeding 4 V may cause permanent damage. The recommended operating range remains 1.8 V to 3.6 V for reliable performance across the full industrial temperature range.
Does TLV2765IPW support true rail-to-rail input at 1.8 V supply?
Yes, TLV2765IPW supports rail-to-rail input with a common-mode voltage range of −0.2 V to VDD + 0.2 V. At 1.8 V supply, this means inputs can extend 200 mV below ground and 200 mV above VDD - enabling direct interface with ground-referenced sensors and reference voltages without level-shifting circuitry.
How does the shutdown function work on TLV2765IPW?
TLV2765IPW has two independent shutdown controls: Pin 5 (1/2SHDN) disables Amplifiers 1 and 2, and Pin 10 (2SHDN) disables Amplifiers 3 and 4. Driving either pin low (≤0.6 V) places its associated pair into shutdown, reducing per-channel supply current to 10 nA. Turn-on time is 5 μs; turn-off time is 0.8 μs - measured from SHDN transition to 50% IDD settling.
What is the output drive capability of TLV2765IPW at 1.8 V?
At 1.8 V supply, TLV2765IPW delivers ±100 μA output current with VOH ≥1.77 V and VOL ≤25 mV (typical). It can source up to 7 mA and sink up to 10 mA under short-circuit conditions. For sustained loading, output swing remains within 20 mV of rails into 300 kΩ, preserving signal integrity in high-impedance sensor interfaces.
Is TLV2765IPW compatible with standard TSSOP-16 PCB footprints?
Yes, TLV2765IPW uses the industry-standard TSSOP-16 package (PW suffix) with 0.65 mm pitch and 5.0 mm × 4.4 mm body dimensions. Its pinout matches JEDEC MO-153, and the exposed thermal pad is non-functional (no electrical connection), allowing direct use of standard TSSOP-16 land patterns without modification.
