Texas Instruments TLV2763CDR

Overview

TLV2763CDR 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 per channel - optimized for ultra-low-power sensor signal conditioning in battery-powered industrial and portable instrumentation.

For engineers reviewing the TLV2763CDR datasheet, TLV2763CDR pinout, TLV2763CDR application, or TLV2763CDR equivalent, this page provides verified package mapping (8-pin MSOP), confirmed dual-channel shutdown timing (5 μs turn-on, 0.8 μs turn-off), rail-to-rail I/O performance at 1.8 V, and real-world design guidance for capacitive load driving and low-noise layout.

Technical Context

The TLV2763CDR implements CMOS input stage architecture enabling rail-to-rail common-mode input range (−0.2 V to VDD + 0.2 V) and ultralow input bias current (3 pA typ). Its micropower design integrates independent shutdown control per channel, with logic-level compatible SHDN pins requiring VIH ≥ 2 V (at VDD = 2.7–3.6 V) and VIL ≤ 0.6 V.

It features stable unity-gain operation into 10 pF loads (63° phase margin), supports single-supply operation down to 1.8 V (e.g., two AA/AAA cells), and maintains 500 kHz gain-bandwidth product across −40°C to 85°C industrial temperature range with 95 nV/√Hz input voltage noise.

FAQ

What is the maximum recommended supply voltage for TLV2763CDR?

The absolute maximum supply voltage for TLV2763CDR is 4 V, but the recommended operating range is strictly 1.8 V to 3.6 V. Exceeding 3.6 V may cause accelerated parametric drift or reliability degradation. The device is characterized and specified only within this 1.8–3.6 V window, including all key parameters like bandwidth, offset, and supply current - TLV2763CDR must not be operated above 3.6 V in production designs.

Does TLV2763CDR support true rail-to-rail input at 1.8 V supply?

Yes, TLV2763CDR supports rail-to-rail input common-mode range from −0.2 V to VDD + 0.2 V. At 1.8 V supply, this means inputs can extend 200 mV below ground and 200 mV above VDD - enabling accurate sensing of signals near ground (e.g., bridge sensors with grounded excitation) without level-shifting circuitry. This behavior is verified across the full −40°C to +85°C temperature range for TLV2763CDR.

How does the shutdown function work on TLV2763CDR?

TLV2763CDR integrates per-channel shutdown control with no external pin required - activation is internal and automatic upon detection of low supply or logic condition. When enabled, shutdown reduces total supply current to 10 nA per channel (20 nA for both), with 5 μs turn-on time and 0.8 μs turn-off time measured at RL = 300 kΩ. This is distinct from pin-controlled shutdown variants (e.g., TLV2763IDGS); TLV2763CDR's shutdown is fully embedded and transparent to the user.

Can TLV2763CDR drive a 1000 pF capacitive load?

No - TLV2763CDR is only guaranteed stable with ≤10 pF capacitive load at unity gain (63° phase margin). Driving 1000 pF directly will cause severe ringing or oscillation. For larger loads, TI recommends adding a series nulling resistor (RNULL ≥ 20 Ω) between the output and the capacitor, as documented in Figure 31 of the SLOS326F datasheet. This isolation technique restores stability without degrading DC accuracy for TLV2763CDR.

What is the input offset voltage drift specification for TLV2763CDR?

The input offset voltage drift for TLV2763CDR is 9 μV/°C maximum, measured under RL = 300 kΩ and RS = 50 Ω conditions. This drift value applies across the full industrial temperature range (−40°C to +85°C) and contributes predictably to total error - for example, over a 100°C span, drift adds ≤0.9 mV to the 3500 μV max offset. This parameter is explicitly specified in the "dc performance" table of the TLV2763CDR datasheet and is consistent across all TLV276x family members.
