Product details

Overview

TLV2764IPWR 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, features 500 kHz bandwidth and 0.20 V/μs slew rate, and supports industrial temperature range (−40°C to +85°C). It is used in ultra-low-power sensor signal conditioning and battery-powered instrumentation.

For engineers reviewing the TLV2764IPWR datasheet, TLV2764IPWR pinout, TLV2764IPWR application, or TLV2764IPWR equivalent, this page delivers verified electrical specs, TSSOP-14 package details, real-world use cases in portable medical devices and energy-harvesting systems, and two validated alternative op-amps with functional trade-offs.

Technical Context

The TLV2764IPWR implements CMOS input stage architecture enabling rail-to-rail common-mode input voltage range (−0.2 V to VDD + 0.2 V) and rail-to-rail output swing within 30 mV of rails at 100 μA load. Its shutdown logic accepts TTL-compatible thresholds (VIH ≥ 2 V, VIL ≤ 0.6 V at VDD = 2.7–3.6 V), and turn-on/turn-off times are 5 μs and 0.8 μs respectively.

Each channel delivers 5 mA output drive capability, maintains 95 nV/√Hz input voltage noise at 1 kHz, and achieves 63° phase margin into 100 pF capacitive load. The device is characterized across supply voltages (1.8 V, 2.4 V, 3.6 V) and full industrial temperature range, with input offset voltage specified at 550 μV (typ) and 3500 μV (max) at 25°C.

Pinout & Package

TSSOP-14 (PW) package: 4.4 mm × 5.0 mm body, 0.65 mm pitch, 14-pin thin shrink small-outline package with exposed pad (no thermal pad connection required per datasheet).

Pin/Terminal	Circuit Role	Design Meaning
1	1OUT	Output of Channel 1 - Rail-to-rail capable, drives up to ±5 mA into resistive loads.
2	1IN−	Inverting input of Channel 1 - High-impedance CMOS node (IIB = 3 pA typ), supports megaohm feedback networks.
3	1IN+	Non-inverting input of Channel 1 - Matches 1IN−; common-mode range extends 0.2 V beyond rails.
4	GND	Analog ground reference - Must be connected to low-impedance PCB ground plane; shared by all four channels.

13	GND	Second analog ground terminal - Internally tied to Pin 4; improves PSRR and reduces ground bounce in multi-channel layout.
14	3/4SHDN	Shared shutdown control for Channels 3 & 4 - Independent of 1/2SHDN; allows asymmetric channel enable/disable sequencing.

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
TLV2454IDR	Higher supply current (23 μA/ch vs. 20 μA), wider supply range (2.7–6 V), no shutdown function.	Lacks per-pair shutdown; requires external FET or regulator for power gating; better for fixed-supply industrial PLC modules.	Select when shutdown is unnecessary and higher supply voltage tolerance (up to 6 V) is required for legacy 3.3 V/5 V systems.
LP324DTBR2G	Lower cost, no rail-to-rail input (common-mode range excludes negative rail), 100 μA/ch supply current.	Cannot interface directly to 0 V-referenced sensors at 1.8 V; unsuitable for battery voltage monitoring near cutoff.	Select only for non-critical, cost-sensitive applications where rail-to-rail input is not required and supply is ≥2.7 V.

Compared with TLV2764IPWR, TLV2454IDR trades shutdown capability for broader supply flexibility and slightly higher quiescent current, while LP324DTBR2G sacrifices rail-to-rail input and micropower operation for cost reduction - making TLV2764IPWR uniquely suited for battery-constrained, low-voltage, multi-channel shutdown-aware designs.

FAQ

What is the maximum recommended supply voltage for TLV2764IPWR?

The absolute maximum supply voltage for TLV2764IPWR is 4 V, but the recommended operating maximum is 3.6 V per the datasheet. Exceeding 3.6 V may cause parametric shift or reliability degradation. Operation at 3.6 V is fully characterized for parameters including bandwidth, output swing, and shutdown current - making it the safe upper limit for long-term design use.

Does TLV2764IPWR support true rail-to-rail input at 1.8 V supply?

Yes, TLV2764IPWR 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 be driven from −0.2 V to +2.0 V - fully covering the supply rails and enabling direct interface to 0 V-referenced sensors like thermistors or bridge outputs without level-shifting circuitry.

How does the shutdown functionality work on TLV2764IPWR?

TLV2764IPWR has two independent shutdown pins: Pin 9 (1/2SHDN) controls Channels 1 and 2; Pin 14 (3/4SHDN) controls Channels 3 and 4. A logic high (≥2 V) enables the associated pair; a logic low (≤0.6 V) places them in ultralow-power shutdown with 10 nA typical supply current per channel - verified across −40°C to +85°C.

What is the output drive capability of TLV2764IPWR at 1.8 V supply?

At 1.8 V supply, TLV2764IPWR delivers ±5 mA output current (sourcing/sinking) while maintaining rail-to-rail swing within 30 mV of the rails at 100 μA load. Short-circuit output current is 7 mA (sourcing) and 10 mA (sinking) - sufficient to drive 300 kΩ feedback networks, LED indicators, or low-power ADC reference buffers without external buffering.

Is TLV2764IPWR pin-compatible with other devices in the TLV276x family?

No - TLV2764IPWR uses a 14-pin TSSOP (PW) package, while TLV2760/TLV2761 use 5-/6-pin SOT-23, and TLV2762/TLV2763 use 8-/10-pin MSOP. Pinouts differ significantly across packages; the TSSOP-14 layout is unique to the quad variants (TLV2764/TLV2765) and not interchangeable with dual or single versions.
