Product details
Overview
TLV2764CD from Texas Instruments is a quad-channel, 1.8 V micropower rail-to-rail input/output operational amplifier with individual shutdown control per channel pair, featuring 500 kHz gain-bandwidth, 20 μA per channel supply current, 550 μV input offset voltage, and operation from 1.8 V to 3.6 V - ideal for battery-powered sensor signal conditioning in portable medical devices.
For engineers reviewing the TLV2764CD datasheet, TLV2764CD pinout, TLV2764CD application, or TLV2764CD equivalent, this page delivers verified electrical specs, TSSOP-14 package mapping, real-world use cases in low-voltage analog front-ends, and two validated alternative op-amps with documented functional trade-offs.
Technical Context
The TLV2764CD integrates four independent CMOS op-amps sharing a common shutdown control architecture that enables dual-channel enable/disable via pins 1/2SHDN (pins 6 & 13) and 3/4SHDN (pins 9 & 16), supporting staggered power management in multi-stage signal chains. Its rail-to-rail input stage operates from −0.2 V to VDD + 0.2 V, while output swing reaches within 25 mV of rails at 100 μA load.
Designed for ultra-low-power precision, it achieves 95 nV/√Hz input voltage noise at 1 kHz and maintains stable unity-gain operation with ≥63° phase margin into 100 pF capacitive loads - critical for driving ADC inputs or driving high-impedance sensor networks without oscillation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.8 V to 3.6 V - supports direct operation from two AA/AAA cells (1.8 V end-of-life) or NiMH/NiCd (2.4 V nominal). |
| Supply Current/Ch | 20 μA typical - enables >1-year battery life in continuous-sensing applications using CR2032 coin cells. |
| Shutdown Current | 10 nA per channel - reduces system standby power to nanoampere level when channels are disabled. |
| Input Offset Voltage | 550 μV max at 25°C - ensures <±1 mV error in 12-bit ADC interfacing at 3.3 V full-scale range. |
| Gain-Bandwidth | 500 kHz - sufficient for anti-aliasing filters up to ~50 kHz and sensor amplification in wearable biosensors. |
| Slew Rate | 0.20 V/μs - supports 100 kHz full-power bandwidth for 1 VPP signals without distortion. |
| Input Common-Mode Range | −0.2 V to VDD + 0.2 V - allows direct interface to unbuffered thermistor or bridge sensor outputs near ground or rail. |

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 |
|---|---|---|---|
| TLV2464CD | Higher supply current (550 μA/ch), wider VDD range (2.7–6 V), no shutdown function. | Better for higher-speed, higher-precision applications where power budget allows >2× current draw. | Select TLV2464CD only if GBW >6 MHz and VIO <150 μV are required - not suitable for sub-100 μA systems. |
| LP324DR | Lower cost, no rail-to-rail input, 3 V minimum VDD, 120 μA/ch supply, no shutdown. | Acceptable for legacy 3.3 V industrial controls where input common-mode range above 0.3 V is acceptable. | Choose LP324DR only for cost-sensitive, non-battery applications with ample headroom - incompatible with 1.8 V or rail-referenced sensors. |
Compared with TLV2764CD, TLV2464CD trades 27× higher supply current for 12× greater bandwidth and lower offset, while LP324DR sacrifices rail-to-rail input, shutdown, and 1.8 V operation to reduce unit cost - making TLV2764CD uniquely suited for ultra-low-power, single-cell, precision analog front-ends.

FAQ
What is the maximum recommended supply voltage for TLV2764CD?
The absolute maximum supply voltage for TLV2764CD is 4 V, but the recommended operating range is strictly 1.8 V to 3.6 V per the datasheet. Exceeding 3.6 V risks parametric shift and accelerated aging; operation at 3.6 V is validated for full temperature range (0°C to 70°C) and yields optimal slew rate and output drive capability.
Does TLV2764CD support true rail-to-rail input at 1.8 V supply?
Yes, TLV2764CD guarantees rail-to-rail input operation from −0.2 V to VDD + 0.2 V across its full temperature range. At 1.8 V supply, this means the input common-mode range extends from −0.2 V to +2.0 V - enabling direct connection to grounded sensors or reference voltages without level-shifting circuitry.
How does the shutdown functionality work on TLV2764CD?
TLV2764CD implements dual-pair shutdown: pins 6 (1/2SHDN) and 13 (3/4SHDN) control Channels 1–2 and Channels 3–4 independently. A logic-high voltage ≥2 V (at VDD = 2.7–3.6 V) enables the pair; logic-low ≤0.6 V disables it, reducing supply current per channel to 10 nA. Turn-on time is 5 μs, turn-off time is 0.8 μs.
Can TLV2764CD drive a 100 pF capacitive load without oscillation?
Yes, TLV2764CD maintains ≥63° phase margin into 100 pF loads at unity gain (RL = 300 kΩ), as confirmed in Figure 18 of the datasheet. This stability eliminates the need for external series isolation resistors when driving SAR ADC input capacitors or long PCB traces - simplifying layout and preserving signal integrity.
What is the input bias current specification for TLV2764CD?
TLV2764CD specifies input bias current of 3 pA typical and 100 pA maximum (C-suffix, 0°C to 70°C). This ultra-low value enables use with megaohm-level feedback and source impedances - critical for pH electrode buffers, piezoelectric sensor interfaces, and high-impedance photodiode transimpedance amplifiers without significant offset drift.
