Texas Instruments TLV2763CD

Overview

TLV2763CD from Texas Instruments is a dual-channel, micropower, rail-to-rail input/output operational amplifier with shutdown control, operating from 1.8 V to 3.6 V supply. It delivers 500 kHz bandwidth and 0.20 V/μs slew rate at only 20 μA per channel, with 550 μV input offset voltage and 10 nA shutdown current - optimized for battery-powered sensor signal conditioning and low-voltage analog front-ends.

For engineers reviewing the TLV2763CD datasheet, TLV2763CD pinout, TLV2763CD application, or TLV2763CD equivalent, key selection criteria include its ultralow 20 μA supply current, rail-to-rail I/O swing at 1.8 V, integrated shutdown functionality with 5 μs turn-on time, and MSOP-8 packaging suitable for space-constrained industrial and portable designs.

Technical Context

The TLV2763CD implements 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 10–30 mV of rails at ±100 μA load. Its micropower design uses optimized biasing to maintain 500 kHz unity-gain bandwidth and 63° phase margin across 1.8–3.6 V supply while supporting stable operation into 10 pF capacitive loads.

Shutdown control is implemented via dedicated SHDN pin (Pin 5), asserting logic-low (<0.6 V) to reduce per-channel supply current to 10 nA. The device features internal ESD protection (>2 kV HBM), operates over 0°C to 70°C (C-suffix), and is characterized for precision performance at 1.8 V - matching end-of-life two-cell alkaline battery voltage.

Key Specifications

Pinout & Package

TLV2763CD is housed in an 8-pin MSOP (DGK) package with 0.65 mm pitch, 3.0 mm × 3.0 mm footprint, and exposed thermal pad (not electrically connected). Pin 1 is marked by a dot; pin numbering follows standard MSOP convention (counterclockwise from mark).

FAQ

What is the maximum recommended supply voltage for TLV2763CD?

The absolute maximum supply voltage for TLV2763CD is 4 V, but the recommended operating range is strictly 1.8 V to 3.6 V. Operation above 3.6 V risks parametric degradation and reduced reliability. This 3.6 V limit ensures compatibility with two-cell alkaline (3.2 V fresh) and Li-ion (4.2 V max) systems when used with appropriate regulation - TLV2763CD itself must not be directly connected to unregulated Li-ion.

Does TLV2763CD support true rail-to-rail input at 1.8 V supply?

Yes, TLV2763CD supports rail-to-rail input common-mode range from −0.2 V to VDD + 0.2 V at all supply voltages including 1.8 V. This allows direct interfacing with grounded sensors and DAC outputs without level-shifting circuitry. Verified across temperature (0°C to 70°C) and process corners, this specification is guaranteed in the datasheet - TLV2763CD maintains input functionality even when VIN falls 0.2 V below GND or rises 0.2 V above VDD.

How does the shutdown function behave on TLV2763CD?

TLV2763CD uses an active-high shutdown pin (Pin 5). Driving SHDN ≥2 V places both amplifiers into ultralow-power state with 10 nA per-channel supply current; pulling SHDN ≤0.6 V fully enables both channels. Turn-on time is 5 μs, turn-off time is 0.8 μs - defined as time for supply current to reach 50% of final value. No external pull-up/down is required; the pin has CMOS-compatible thresholds referenced to GND - TLV2763CD remains functional across its full temperature range under shutdown.

Can TLV2763CD drive capacitive loads, and what is the recommended approach?

TLV2763CD is stable with ≤10 pF capacitive load at unity gain. For larger loads (e.g., ADC input capacitance, cable capacitance), a series null resistor (RNULL ≥20 Ω) must be placed between TLV2763CD output and the load to preserve phase margin and prevent ringing. This is documented in the datasheet's "Driving a Capacitive Load" section (Figure 31). Without RNULL, loads >10 pF degrade stability - TLV2763CD's 63° phase margin assumes proper layout and minimal parasitic capacitance.

What is the input bias current specification for TLV2763CD, and why does it matter?

TLV2763CD specifies maximum input bias current of 15 pA at 25°C (100 pA over full 0°C to 70°C range). This ultra-low value enables use with megaohm-level feedback and source impedances without significant offset error - critical in high-impedance sensor interfaces like pH electrodes or photodiode transimpedance amplifiers. At 10 MΩ source impedance, 15 pA bias contributes only 150 μV offset - TLV2763CD's 550 μV VIO dominates, but bias current remains negligible in precision designs.
