Product details
Overview
TLV2764IPW 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 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 TLV2764IPW datasheet, TLV2764IPW pinout, TLV2764IPW application, or TLV2764IPW equivalent, key selection criteria include its 10 nA shutdown current per channel, rail-to-rail I/O at 1.8 V, 550 μV input offset voltage, TSSOP-14 package footprint, and compatibility with single-cell AA/AAA or NiMH/NiCd supplies.
Technical Context
The TLV2764IPW integrates four independent CMOS op-amps with dedicated shutdown pins (1/2SHDN on Pin 8, 3/4SHDN on Pin 15), enabling selective channel disable to minimize system-level quiescent current. Its rail-to-rail input stage accepts common-mode voltages from −0.2 V to VDD + 0.2 V, and rail-to-rail output swings within 25 mV of rails at 100 μA load.
Designed for low-voltage precision analog front-ends, it features 95 nV/√Hz input voltage noise, 0.8 fA/√Hz input current noise, and 63° phase margin into 100 pF loads - supporting stable operation with minimal external compensation in portable measurement circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 3.6 V - enables direct operation from two alkaline (1.8 V end-of-life) or NiMH (2.4 V nominal) cells. |
| Supply Current (per channel) | 20 μA - allows continuous sensing for years on coin-cell or small Li-ion batteries. |
| Shutdown Current (per channel) | 10 nA - reduces total system standby power to sub-50 nA when all channels disabled. |
| Input Offset Voltage | 550 μV - supports accurate DC-coupled amplification of mV-level sensor outputs without trimming. |
| Unity-Gain Bandwidth | 500 kHz - sufficient for anti-aliasing, active filtering, and fast-settling (<14 μs to 0.01%) data acquisition. |
| Rail-to-Rail I/O | Yes - maximizes dynamic range at 1.8 V supply, eliminating need for level-shifting in low-voltage systems. |
| Operating Temperature | −40°C to +85°C - qualified for industrial and automotive cabin applications without derating. |
Pinout & Package
TSSOP-14 (PW) package: 4.4 mm × 5.0 mm, 0.65 mm pitch, thermally enhanced with exposed pad (not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of Channel 1 - drives loads up to ±5 mA with rail-to-rail swing. |
| 2 | 1IN− | Inverting input of Channel 1 - high-impedance CMOS node (3 pA bias current). |
| 3 | 1IN+ | Non-inverting input of Channel 1 - accepts signals from −0.2 V to VDD + 0.2 V. |
| 4 | GND | Analog ground reference - must be tied to low-impedance system ground plane. |
| 5 | VDD | Positive supply - decoupled with 0.1 μF ceramic capacitor placed ≤0.1 inch from pin. |
| 6 | 2IN+ | Non-inverting input of Channel 2 - independent of Channel 1; supports differential pair configurations. |
| 7 | 2IN− | Inverting input of Channel 2 - matched to Pin 2 for common-mode rejection. |
| 8 | 1/2SHDN | Active-high shutdown control for Channels 1 & 2 - pulls supply current to 10 nA/channel when low. |
| 9 | 2OUT | Output of Channel 2 - electrically isolated from Channel 1; no crosstalk above −120 dB @ 1 kHz. |
| 10 | 4OUT | Output of Channel 4 - identical performance to Pins 1 and 9; supports multi-channel feedback loops. |
| 11 | 4IN− | Inverting input of Channel 4 - referenced to same GND as all other inputs. |
| 12 | 4IN+ | Non-inverting input of Channel 4 - usable for parallel sensor inputs or gain-stage buffering. |
| 13 | GND | Second ground terminal - improves PSRR and thermal stability; tied to same net as Pin 4. |
| 14 | 3IN+ | Non-inverting input of Channel 3 - enables independent configuration of fourth amplifier channel. |
| 15 | 3/4SHDN | Active-high shutdown control for Channels 3 & 4 - allows staggered wake-up sequencing in firmware. |
| 16 | 3OUT | Output of Channel 3 - fully specified for 100 μA load at 1.8 V; maintains rail-to-rail swing. |
Key Features
| Feature | Design Value |
|---|---|
| 1.8 V operation with rail-to-rail I/O | Enables full signal swing in energy-harvesting and wearable systems where supply headroom is <200 mV. |
| 20 μA per channel supply current | Reduces total quiescent power to 80 μA for all four channels - critical for always-on environmental monitors. |
| 10 nA per channel shutdown current | Allows deep-sleep modes with negligible leakage, extending shelf life of sealed battery-powered devices. |
| Dual independent shutdown controls | Permits partial activation (e.g., keep Channel 1 awake for wake-on-event while shutting down others). |
| 95 nV/√Hz input voltage noise | Preserves SNR in low-frequency sensor interfaces (e.g., thermopiles, strain gauges) without added filtering. |
| Specified for −40°C to +85°C | Eliminates need for external temperature compensation in industrial PLC analog input modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op-amp with shutdown applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2764CDR | Same silicon, SOIC-14 package (5.0 mm × 6.2 mm), commercial temp (0°C to 70°C), no exposed pad. | Larger footprint; unsuitable for space-constrained portable designs; not rated for extended temperature operation. | Select when board area is unconstrained and industrial temp range is unnecessary. |
| LP324DTBR | Quad op-amp with 45 μA/channel supply current, no shutdown, 3 V to 30 V range, 100 kHz GBW. | Higher power, wider supply, lower bandwidth; lacks rail-to-rail I/O and shutdown capability. | Select only if supply exceeds 3.6 V or shutdown is not required and cost is primary constraint. |
Compared with TLV2764IPW, TLV2764CDR offers identical electrical performance but larger SOIC packaging and narrower temperature range, while LP324DTBR trades micropower and shutdown for higher voltage tolerance and lower unit cost - making TLV2764IPW uniquely suited for compact, battery-operated, wide-temp industrial sensing.

FAQ
What is the maximum supply voltage for TLV2764IPW?
The absolute maximum supply voltage for TLV2764IPW 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. All specifications - including 20 μA supply current and 550 μV offset - are guaranteed only within this 1.8–3.6 V window. The TLV2764IPW datasheet explicitly states 3.6 V as the upper limit for normal operation.
Does TLV2764IPW support true rail-to-rail input and output?
Yes, TLV2764IPW supports true rail-to-rail input and output. Its CMOS input stage accepts common-mode voltages from −0.2 V to VDD + 0.2 V, and its output swings to within 25 mV of both rails under 100 μA load. This is confirmed in the "Electrical Characteristics" table (page 6) and "Recommended Operating Conditions" (page 4) of the TLV2764IPW datasheet, enabling full dynamic range utilization at 1.8 V supply.
How does the shutdown function work on TLV2764IPW?
TLV2764IPW has two independent shutdown controls: Pin 8 (1/2SHDN) disables Channels 1 and 2, and Pin 15 (3/4SHDN) disables Channels 3 and 4. Both are active-high; driving either pin low reduces the respective channels' supply current to 10 nA. Turn-on time is 5 μs and turn-off time is 0.8 μs (measured to 50% IDD), as specified in the "Shutdown Characteristics" table (page 7) of the TLV2764IPW datasheet.
What is the input offset voltage specification for TLV2764IPW?
The input offset voltage for TLV2764IPW is 550 μV (typical) and 3500 μV (maximum) at 25°C, and 6800 μV (maximum) across the full −40°C to +85°C industrial temperature range. This value is measured with VIC = VDD/2 and VO = VDD/2 at RL = 300 kΩ, as defined in the "DC Performance" section (page 5) of the TLV2764IPW datasheet.
Is TLV2764IPW pin-compatible with other TLV276x variants?
No, TLV2764IPW is not pin-compatible with TLV2760/1 (SOT-23), TLV2762/3 (MSOP), or TLV2765 (TSSOP-16). It uses a unique TSSOP-14 (PW) footprint with dual shutdown pins (Pins 8 and 15) and duplicated ground pins (Pins 4 and 13). Pin mapping is explicitly shown in the "TLV276x PACKAGE PINOUTS" diagram (page 3) of the TLV2764IPW datasheet - confirming no mechanical or functional pin alignment with other family members.
