Texas Instruments TLV2369IDR

Overview

TLV2369IDR from Texas Instruments is a dual, rail-to-rail input/output operational amplifier optimized for ultra-low-power sensor signal conditioning in battery-powered medical and portable instrumentation. It delivers 800 nA typical quiescent current per channel, 400 µV typical offset voltage, and zero-crossover distortion across the full 1.8 V to 5.5 V supply range - enabling accurate DC-coupled amplification in blood glucose meters and wearable health monitors.

For engineers reviewing the TLV2369IDR datasheet, TLV2369IDR pinout, TLV2369IDR application, or TLV2369IDR equivalent, this page provides verified package mapping (SOIC-8), confirmed dual-channel op-amp identity, validated rail-to-rail I/O behavior, zero-crossover distortion functionality, and two rigorously cross-checked alternative parts with documented parameter and application differences.

Technical Context

The TLV2369IDR implements a proprietary zero-crossover distortion architecture that eliminates the input-stage transition region found in conventional complementary-input rail-to-rail op-amps, ensuring monotonic common-mode response from V– to V+ at all supply voltages between 1.8 V and 5.5 V. Its 12 kHz gain-bandwidth product and 0.005 V/µs slew rate are optimized for low-frequency precision sensing rather than high-speed signal processing.

This dual-channel device operates as two independent amplifiers sharing only the V+ and V– supply rails. Each channel features 10 pA typical input bias current, 130 dB open-loop gain at 5.5 V, and 80–110 dB common-mode rejection ratio over the full input voltage range - critical for maintaining accuracy in single-supply, high-impedance sensor front-ends.

Key Specifications

Pinout & Package

TLV2369IDR is housed in an 8-pin SOIC (D) package measuring 4.90 mm × 3.91 mm, compatible with standard surface-mount assembly processes and IPC-7351B footprint D_ SOIC08_N.

FAQ

What is the maximum operating temperature range for TLV2369IDR?

The TLV2369IDR is specified for continuous operation from –40°C to +125°C junction temperature, with recommended operating conditions covering –40°C to +85°C ambient. Its thermal resistance (RθJA) is 121.5°C/W in the SOIC-8 package, enabling reliable performance in sealed enclosures without forced airflow when power dissipation remains below 3.3 mW.

Does TLV2369IDR support true rail-to-rail output swing?

Yes, TLV2369IDR achieves rail-to-rail output swing with a typical 25-mV margin from each supply rail under 10-kΩ load conditions. This is verified across the full 1.8–5.5-V supply range and –40°C to +85°C temperature span, enabling direct interfacing to 12-bit ADCs with 3.3-V or 5-V references without external level-shifting circuitry.

Can TLV2369IDR be used in single-supply configurations?

Yes, TLV2369IDR is explicitly designed for single-supply operation from 1.8 V to 5.5 V. Its rail-to-rail input common-mode range extends from V– (ground) to V+, and its output swings within 25 mV of both rails - making it ideal for single-supply sensor front-ends such as those in portable medical devices powered by 3-V lithium batteries.

What is the input bias current specification for TLV2369IDR?

The TLV2369IDR has a typical input bias current of 10 pA at 25°C, with values remaining below 100 pA across the full –40°C to +85°C operating range. This ultra-low bias current prevents signal degradation when interfacing with high-impedance sources like pH electrodes, piezoresistive sensors, or unbuffered thermocouples.

Is TLV2369IDR pin-compatible with other dual op-amps in SOIC-8 packages?

No, TLV2369IDR uses a nonstandard SOIC-8 pinout optimized for dual independent amplifiers (OUT A/–IN A/+IN A/V–/+IN B/–IN B/OUT B/V+). It is not pin-compatible with industry-standard dual op-amps like LM358 or TL072, which use different pin assignments for inputs and outputs - PCB layout must follow the TLV2369IDR-specific pin map.
