Product details
Overview
TLV2764IN 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 shutdown current per channel - used in ultra-low-power sensor signal conditioning and battery-powered instrumentation.
For engineers reviewing the TLV2764IN datasheet, TLV2764IN pinout, TLV2764IN application, or TLV2764IN equivalent, this page delivers verified electrical parameters, industrial-grade thermal performance, TSSOP-14 package layout, and real-world substitution guidance for low-voltage precision analog design.
Technical Context
The TLV2764IN employs 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), critical for 1.8 V single-supply systems. Its micropower design integrates ultralow input bias current (3 pA typ) and high input impedance (>1 GΩ), supporting high-impedance sensor interfaces without significant error.
Each of its four amplifiers features independent active-high shutdown control (SHDN pins), with fast enable/disable timing (5 μs turn-on, 0.8 μs turn-off) and <400 nA per-channel shutdown current. The device operates across 1.8 V–3.6 V supply, with PSRR of 63–85 dB and CMRR of 48–82 dB depending on voltage and temperature.
Key Specifications

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplifier A output - rail-to-rail capable, drives 10 kΩ load to within 25 mV of rails |
| 2 | 1IN− | Inverting input of Amp A - high-impedance CMOS node (3 pA bias current) |
| 3 | 1IN+ | Non-inverting input of Amp A - accepts signals from −0.2 V to VDD + 0.2 V |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad micropower op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2454IN | Higher supply current (23 μA/ch), no shutdown, wider VDD (2.7–6 V), 0.22 V/μs slew rate | Lacks shutdown capability; unsuitable for duty-cycled or ultra-low-power systems | Choose when higher bandwidth (650 kHz) and rail-to-rail output are needed without shutdown control |
| LP324N | Lower supply current (15 μA/ch), no rail-to-rail I/O, wider VDD (3–32 V), no shutdown, −40°C to +105°C | Input common-mode range excludes rails; cannot interface directly with 1.8 V ADC references | Choose for wide-supply industrial sensors where rail-to-rail is not required and extended temp is critical |
Compared with TLV2454IN and LP324N, the TLV2764IN uniquely combines 1.8 V operation, per-pair shutdown, rail-to-rail I/O, and industrial temperature rating - making it the only option for compact, battery-constrained, precision analog front ends requiring full signal swing at sub-2 V supplies.

FAQ
What is the maximum supply voltage for TLV2764IN?
The absolute maximum supply voltage for TLV2764IN is 4 V, but the recommended operating range is strictly 1.8 V to 3.6 V. Exceeding 3.6 V risks parametric degradation and reduced reliability, especially at elevated temperatures. Operation at 3.6 V is valid and supported across the full −40°C to +85°C range, with supply current rising to 30 μA per channel.
Does TLV2764IN support true rail-to-rail input at 1.8 V supply?
Yes, TLV2764IN supports rail-to-rail input common-mode range from −0.2 V to VDD + 0.2 V at 1.8 V supply. This allows direct interfacing with 0 V-referenced sensors and ADC references without level-shifting, confirmed by datasheet Figure 1 and Table "Common-mode input voltage range" under recommended operating conditions.
How does the shutdown function work on TLV2764IN?
TLV2764IN has two independent shutdown controls: Pin 8 (1/2SHDN) disables Amplifiers A and B; Pin 14 (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 disables them, reducing supply current to ≤400 nA per channel. Turn-on time is 5 μs, turn-off time is 0.8 μs.
Can TLV2764IN drive a 10 kΩ load while maintaining rail-to-rail output swing?
Yes - at VDD = 1.8 V and TA = 25°C, TLV2764IN delivers VOH ≥1.77 V and VOL ≤30 mV into 100 μA load, and VOH ≥1.725 V and VOL ≤75 mV into 500 μA load. For a 10 kΩ load (180 μA at 1.8 V), output swing remains within 25 mV of each rail, satisfying rail-to-rail specification per datasheet Section "Output Characteristics".
Is TLV2764IN pin-compatible with other TLV276x variants in TSSOP-14?
Yes - TLV2764IN shares identical TSSOP-14 (PW) pinout and footprint with TLV2764CD, TLV2764ID, and TLV2764IPW. All TLV2764-x variants use the same 14-pin assignment shown in Figure "TLV2764 D, N, OR PW PACKAGE" on page 3 of the datasheet, including shared shutdown pins and channel grouping.
