Texas Instruments TLV2765IDR

Overview

TLV2765IDR 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, achieves 500 kHz gain-bandwidth, 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 TLV2765IDR datasheet, TLV2765IDR pinout, TLV2765IDR application, or TLV2765IDR equivalent, key selection criteria include shutdown current (10 nA/channel), rail-to-rail I/O at 1.8 V, input offset voltage (550 μV typ), low-noise performance (95 nV/√Hz), and TSSOP-16 package compatibility with space-constrained PCB layouts.

Technical Context

The TLV2765IDR 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 15–75 mV of supply rails. Its micropower design uses optimized biasing to maintain 500 kHz bandwidth and 0.20 V/μs slew rate while consuming just 20 μA per channel at 1.8 V.

Each of its four amplifiers features independent active-low SHDN pins (pins 5, 10, 13, 16), allowing selective channel disabling with 10 nA shutdown current per channel. The device is characterized across −40°C to +85°C and specified for 1.8 V operation - critical for two-cell alkaline/NiMH battery systems where supply drops to 0.9 V per cell at end-of-life.

FAQ

What is the maximum recommended supply voltage for TLV2765IDR?

The absolute maximum supply voltage for TLV2765IDR 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. At 3.6 V, the device delivers improved PSRR (65 dB) and output drive (±7.3 mA), but quiescent current increases only marginally to 28 μA per channel - still well within micropower classification.

Does TLV2765IDR support true rail-to-rail input at 1.8 V supply?

Yes, TLV2765IDR 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 swing from −0.2 V to +2.0 V - fully encompassing the supply rails and enabling accurate amplification of signals referenced to ground or VDD/2 without clipping.

How does the shutdown functionality work on TLV2765IDR?

TLV2765IDR provides four independent active-low SHDN pins (pins 5, 10, 13, 16), one per amplifier channel. Driving any SHDN pin low reduces that channel's supply current to ≤400 nA (typ 10 nA) while placing its output in high-impedance state. All four channels remain fully functional and independently controllable - no inter-channel coupling or timing dependencies exist in TLV2765IDR shutdown behavior.

What is the typical input offset voltage of TLV2765IDR and how does it vary with temperature?

The typical input offset voltage of TLV2765IDR is 550 μV at 25°C, with a maximum of 3500 μV over the full −40°C to +85°C range. Its offset drift is specified at 9 μV/°C, meaning total offset variation across the industrial temperature range is approximately ±765 μV - resulting in worst-case total offset of ~4265 μV, which remains manageable in 12-bit systems with gain ≤5.

Can TLV2765IDR drive a 10 kΩ load while maintaining rail-to-rail output swing?

Yes, TLV2765IDR maintains rail-to-rail output swing into 10 kΩ loads: at 1.8 V supply, VOH ≥ 1.76 V and VOL ≤ 30 mV (IOL = 100 μA); at 2.4 V, VOH ≥ 2.37 V and VOL ≤ 75 mV (IOL = 500 μA). This ensures ≥98% of full-scale output range is usable - critical for maximizing resolution in low-voltage ADC interfaces without external level-shifting.
