Product details
Overview
TLV2764IDR from Texas Instruments is a quad-channel, micropower, rail-to-rail input/output operational amplifier optimized for 1.8 V single-supply operation. It delivers 500 kHz bandwidth, 20 μA per channel supply current, and 10 nA shutdown current, enabling ultra-low-power sensor signal conditioning in battery-powered industrial and portable instrumentation.
For engineers reviewing the TLV2764IDR datasheet, TLV2764IDR pinout, TLV2764IDR application, or TLV2764IDR equivalent, key selection criteria include its 1.8–3.6 V supply range, −40°C to 85°C industrial temperature grade, TSSOP-14 package, and integrated shutdown control per amplifier pair - critical for power-gated multi-channel analog front-ends.
Technical Context
The TLV2764IDR implements CMOS input stage architecture with rail-to-rail common-mode input range (−0.2 V to VDD + 0.2 V) and rail-to-rail output swing, ensuring full dynamic range utilization at 1.8 V supply. Its 550 μV typical input offset voltage and 95 nV/√Hz input voltage noise support precision DC-coupled amplification.
Each of the four amplifiers features independent shutdown control via dedicated SHDN pins (pins 6 and 13), enabling selective channel disable with 5 μs turn-on and 0.8 μs turn-off times. The device operates across 1.8–3.6 V with guaranteed performance at both 1.8 V (end-of-life dual AA/AAA) and 2.4 V (nominal NiMH/NiCd) supply points.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2454CDR | Higher supply current (23 μA/ch), no shutdown, wider supply (2.7–6 V), higher GBW (220 kHz) | Lacks shutdown and 1.8 V operation - unsuitable for coin-cell or energy-harvesting use cases | Select when higher speed and rail-to-rail output are needed but 1.8 V operation and nanoamp shutdown are not required |
| LP324DR | No rail-to-rail input/output, higher offset (3 mV), no shutdown, lower supply current (45 μA/ch), wider temp range (−40°C to 105°C) | Cannot interface directly with 1.8 V ADCs due to limited output swing; requires external level-shifting | Select for cost-sensitive industrial applications where 1.8 V operation and rail-to-rail performance are not mandatory |
Compared with TLV2454CDR and LP324DR, the TLV2764IDR uniquely combines 1.8 V operation, rail-to-rail I/O, and 10 nA shutdown - making it the only viable option for long-life, low-voltage, multi-channel sensor systems requiring dynamic power gating.

FAQ
What is the maximum recommended supply voltage for TLV2764IDR?
The absolute maximum supply voltage for TLV2764IDR is 4 V, but the recommended operating range is strictly 1.8 V to 3.6 V. Exceeding 3.6 V may cause parametric degradation or reliability issues. All electrical specifications in the datasheet are guaranteed only within this 1.8–3.6 V window, and TLV2764IDR is characterized for optimal performance at 1.8 V (end-of-life battery) and 2.4 V (nominal NiMH).
Does TLV2764IDR support true rail-to-rail input at 1.8 V supply?
Yes, TLV2764IDR supports rail-to-rail input common-mode range from −0.2 V to VDD + 0.2 V at 1.8 V supply. This allows input signals to extend 200 mV below ground and 200 mV above VDD - critical for interfacing with sensors that output near-ground or near-rail voltages. Input bias current remains under 15 pA across this full range, preserving accuracy in high-impedance source applications.
How does the shutdown functionality work on TLV2764IDR?
TLV2764IDR features two independent shutdown controls: pin 6 (1/2SHDN) disables amplifiers A and B, and pin 13 (3/4SHDN) disables amplifiers C and D. A logic-high voltage ≥2 V (at VDD ≥2.7 V) or ≥0.75·VDD (at VDD <2.7 V) enables the associated pair; logic-low ≤0.6 V disables them. Shutdown reduces per-channel supply current to 10 nA, with 5 μs turn-on and 0.8 μs turn-off times - verified across −40°C to 85°C.
Can TLV2764IDR drive capacitive loads without oscillation?
TLV2764IDR is stable with capacitive loads ≤10 pF in unity-gain configuration. For larger loads (e.g., ADC input capacitance or cable termination), a series null resistor (RNULL ≥20 Ω) must be placed between the amplifier output and the load, as specified in TI's SLOS326F datasheet Figure 31. Without RNULL, phase margin degrades below 63°, risking ringing or oscillation - especially at 1.8 V supply where gain-bandwidth is reduced.
What is the input offset voltage drift specification for TLV2764IDR?
The input offset voltage drift for TLV2764IDR is 9 μV/°C, measured over the full industrial temperature range (−40°C to 85°C). This drift value applies to all TLV276x family members and is confirmed in the "Electrical Characteristics" table on page 5 of the SLOS326F datasheet. At 85°C, the total offset (including drift) remains within the 3500 μV maximum limit specified for the I-suffix grade.
