Texas Instruments TLV2453IDGS

Overview

TLV2453IDGS from Texas Instruments is a dual rail-to-rail input/output operational amplifier optimized for ultralow-power, low-voltage portable systems. It delivers 220 kHz gain-bandwidth, ±10 mA output drive, and 23 µA/channel supply current across 2.7 V to 6 V operation, with shutdown capability reducing current to 16 nA/channel. It is used in patient monitoring front-ends where rail-to-rail swing maximizes dynamic range at 3 V.

For engineers reviewing the TLV2453IDGS datasheet, TLV2453IDGS pinout, TLV2453IDGS application, or TLV2453IDGS equivalent, key selection criteria include shutdown functionality, MSOP-10 package footprint, rail-to-rail I/O performance at sub-3 V supplies, and guaranteed operation over −40°C to 125°C industrial temperature range.

Technical Context

The TLV2453IDGS integrates two independent op-amps with separate shutdown controls (1SHDN on Pin 5, 2SHDN on Pin 10) enabling channel-level power gating. Its input stage uses complementary input pairs to achieve rail-to-rail common-mode range, while the output stage employs Class AB architecture to sustain ±10 mA into resistive loads while maintaining rail-to-rail swing under 2.5 mA load.

It operates fully specified at 3 V and 5 V with guaranteed AC performance including 220 kHz GBW and 0.11 V/µs slew rate, alongside DC precision of 20 µV typical input offset voltage and 106 dB PSRR - all while consuming only 23 µA per channel in active mode.

FAQ

What is the operating temperature range for TLV2453IDGS?

The TLV2453IDGS is specified for continuous operation from −40°C to 125°C. This extended industrial temperature range is validated across all key parameters including supply current, input offset voltage, gain-bandwidth product, and shutdown leakage. It enables reliable use in automotive under-hood modules, factory-floor sensors, and outdoor medical telemetry units where ambient extremes are expected. The 'I' suffix in TLV2453IDGS explicitly denotes this temperature grade.

Does TLV2453IDGS support true rail-to-rail input and output operation?

Yes, TLV2453IDGS supports true rail-to-rail input common-mode range (0 V to VDD) and rail-to-rail output swing (within 250 mV of each rail at 2.5 mA load). This is achieved via complementary input differential pairs and a Class AB output stage. At 3 V supply, the output can swing from 0.15 V to 2.85 V with 500 µA load, preserving >90% of full-scale dynamic range - critical for maximizing resolution in low-voltage ADC interfaces.

How does the shutdown feature work on TLV2453IDGS?

TLV2453IDGS features two independent shutdown pins: Pin 5 (1SHDN) controls Amplifier A, and Pin 10 (2SHDN) controls Amplifier B. Driving either pin low (≤0.5 V at VDD = 3 V, ≤0.8 V at VDD = 5 V) disables the corresponding amplifier, placing its output in high-impedance state and reducing its supply current to 16 nA. Both amplifiers remain active when shutdown pins are high (≥2 V). This allows granular power management in multi-channel systems without cross-talk or shared control logic.

What package type is TLV2453IDGS supplied in, and what are its key mechanical attributes?

TLV2453IDGS is supplied in a 10-pin MSOP (DGS) package measuring 3.0 mm × 3.0 mm × 1.0 mm with 0.5 mm lead pitch. It includes an exposed thermal pad (non-electrical) for improved heat dissipation in high-density layouts. The package is RoHS-compliant, halogen-free, and qualified for reflow soldering per JEDEC J-STD-020. Its small footprint supports miniaturized PCBs in wearables and handheld diagnostics tools.

What is the typical input offset voltage of TLV2453IDGS, and how does it vary with temperature?

The typical input offset voltage of TLV2453IDGS is 20 µV at 25°C, with a maximum of 1300 µV over the full −40°C to 125°C range. Its offset voltage drift is specified at 0.3 µV/°C, meaning total drift across the temperature range contributes ≤49.5 µV. This low drift, combined with tight initial offset, ensures minimal DC error accumulation in precision sensor interfaces - such as thermopile amplifiers or strain gauge bridges - without requiring periodic auto-zero calibration.
