Product details
Overview
TLV2765CDR from Texas Instruments is a quad-channel, 1.8 V micropower rail-to-rail input/output operational amplifier with individual shutdown control per channel. It operates from 1.8 V to 3.6 V, draws only 20 μA per channel, delivers 500 kHz bandwidth and 0.20 V/μs slew rate, and features 10 nA shutdown current per channel - optimized for ultra-low-power sensor signal conditioning in battery-powered industrial and portable instrumentation.
For engineers reviewing the TLV2765CDR datasheet, TLV2765CDR pinout, TLV2765CDR application, or TLV2765CDR equivalent, this page provides verified package mapping (16-pin TSSOP), confirmed rail-to-rail I/O performance at 1.8 V, real-world shutdown timing (5 μs turn-on, 0.8 μs turn-off), and validated alternatives for low-voltage, low-quiescent-current op-amp selection.
Technical Context
The TLV2765CDR 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 25 mV of rails at 100 μA load). Its micropower design achieves 20 μA/channel supply current while maintaining 550 μV typical input offset voltage and 95 nV/√Hz input voltage noise at 1 kHz.
Each of the four amplifiers includes independent shutdown control (pins 1/2SHDN and 3/4SHDN), allowing selective channel disablement without affecting others. The device is characterized across −40°C to 85°C and supports stable operation into 10 pF capacitive loads with optional series nulling resistor.

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-voltage, low-power op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2454CDR | Higher supply current (23 μA/channel), no shutdown, wider supply range (2.7–6 V) | Lacks per-channel shutdown; unsuitable for duty-cycled sensor nodes requiring nanoampere standby | Select when higher bandwidth (650 kHz) and rail-to-rail output are needed without shutdown functionality |
| LPV521MG/NOPB | Lower supply current (320 nA/channel), no shutdown, lower bandwidth (10 kHz), single-channel only | Single-channel architecture requires four devices for quad functionality; lacks independent shutdown grouping | Select for ultra-long-life applications where bandwidth <10 kHz suffices and board space allows discrete quad implementation |
Compared with TLV2765CDR, TLV2454CDR offers higher bandwidth but no power-gating capability, while LPV521MG/NOPB achieves extreme quiescent current reduction at the cost of bandwidth and integration - making TLV2765CDR the optimal balance of quad integration, shutdown flexibility, and 500 kHz signal fidelity at 1.8 V.

FAQ
What is the maximum recommended supply voltage for TLV2765CDR?
The absolute maximum supply voltage for TLV2765CDR is 4 V, but the recommended operating range is strictly 1.8 V to 3.6 V. Operation above 3.6 V risks permanent damage and violates TI's specified conditions; designs using 3.3 V or 3.6 V supplies must ensure transient spikes remain below 4 V. This limit is defined in the Absolute Maximum Ratings table of the SLOS326F datasheet.
Does TLV2765CDR support true rail-to-rail input at 1.8 V supply?
Yes, TLV2765CDR supports rail-to-rail input common-mode range from −0.2 V to VDD + 0.2 V at 1.8 V supply, verified across the full industrial temperature range (−40°C to 85°C). This allows direct interfacing with sensors whose output extends below ground or above VDD, such as piezoelectric or certain bridge configurations - a key enabler for single-supply 1.8 V systems.
How does the shutdown function work on TLV2765CDR?
TLV2765CDR features two independent shutdown control pins: Pin 8 (1/2SHDN) disables Amplifiers A and B, and Pin 16 (3/4SHDN) disables Amplifiers C and D. A logic-low voltage (<0.6 V at VDD = 2.7–3.6 V) places the associated pair into shutdown, reducing supply current to 10 nA per channel. Turn-on time is 5 μs, turn-off time is 0.8 μs - confirmed under RL = 300 kΩ load per the datasheet's shutdown characteristics table.
Can TLV2765CDR drive a 10 kΩ load while maintaining rail-to-rail output?
Yes, TLV2765CDR maintains rail-to-rail output swing into 10 kΩ loads: at VDD = 1.8 V, VOH ≥ 1.77 V and VOL ≤ 25 mV (100 μA sink/source); at VDD = 2.4 V, VOH ≥ 2.38 V and VOL ≤ 30 mV. These values are specified in the Output Characteristics table for full industrial temperature range and confirm usable output range exceeds 98% of VDD - sufficient for driving 12-bit ADC references or low-power comparators.
What is the input offset voltage drift over temperature for TLV2765CDR?
The input offset voltage drift for TLV2765CDR is 9 μV/°C (typical), measured across the full industrial temperature range (−40°C to 85°C) with RL = 300 kΩ and RS = 50 Ω. This low drift ensures minimal baseline shift in precision DC-coupled applications like thermopile amplification or strain gauge bridges, where offset stability directly impacts measurement accuracy over environmental changes.
