Texas Instruments TLV2314IDR

Overview

TLV2314IDR from Texas Instruments is a dual-channel, rail-to-rail input/output operational amplifier optimized for low-power, precision signal conditioning in battery-powered and industrial systems. It delivers 3 MHz gain bandwidth, 1.5 V/µs slew rate, 0.75 mV typical offset voltage, 1 pA typical input bias current, and operates from 1.8 V to 5.5 V supply - enabling high-accuracy sensor interfacing in portable blood glucose meters and remote sensing nodes.

For engineers reviewing the TLV2314IDR datasheet, TLV2314IDR pinout, TLV2314IDR application, or TLV2314IDR equivalent, this page provides verified package mapping (SOIC-8), confirmed dual-channel functional behavior, EMI-rejecting internal RF filter performance, and validated alternatives for low-voltage, low-I_Q op-amp selection in space-constrained embedded designs.

Technical Context

The TLV2314IDR employs a complementary differential input stage enabling rail-to-rail common-mode operation down to (V–) – 0.2 V and up to (V+) + 0.2 V, with no phase reversal under overdrive. Its class AB output stage drives ≥10 kΩ loads while maintaining ≤5 mV rail-to-rail swing at 1.8 V supply.

It integrates an internal 80 MHz low-pass EMI filter on both inputs, achieving >60 dB EMIRR at 100 MHz and supporting robust operation in noisy industrial or handheld test environments. Unity-gain stability and support for capacitive loads up to 300 pF simplify layout without external compensation.

FAQ

What is the maximum capacitive load the TLV2314IDR can drive stably in unity-gain configuration?

The TLV2314IDR remains unity-gain stable with capacitive loads up to 300 pF, as verified in the datasheet's Typical Characteristics (Figure 8). For loads exceeding this - such as ADC sample capacitors or long PCB traces - a small series resistor (10–20 Ω) between the output and load restores stability without compromising DC accuracy in most sensor interface applications. This behavior is intrinsic to the TLV2314IDR's internal compensation and applies identically across both channels.

Does the TLV2314IDR support true single-supply operation down to 1.8 V?

Yes, the TLV2314IDR is fully specified and production-tested for operation from 1.8 V to 5.5 V single supply (or ±0.9 V to ±2.75 V dual supply). At 1.8 V, it maintains rail-to-rail input common-mode range (V– – 0.2 V to V+ + 0.2 V), 5 mV output swing to rails, and 3 MHz gain bandwidth - enabling direct interfacing with low-voltage microcontrollers and ADCs without level-shifting circuitry. All key parameters in the Electrical Characteristics table include 1.8 V test conditions.

How does the internal EMI filter in the TLV2314IDR improve system-level robustness?

The TLV2314IDR integrates a monolithic 80-MHz low-pass filter on both input pins, providing >60 dB rejection of RF interference from 100 MHz to 1 GHz - measured as EMIRR IN+. This eliminates external filtering components (e.g., RC networks or ferrite beads) in handheld medical devices and industrial sensors exposed to cellular, Wi-Fi, or switching power supply noise. The filter operates transparently: no external components, no bandwidth sacrifice below 3 MHz, and no impact on DC precision - a key differentiator of the TLV2314IDR versus generic low-power op-amps.

Is the TLV2314IDR pin-compatible with other dual op-amps in SOIC-8 packages?

No - the TLV2314IDR uses a non-standard SOIC-8 pinout optimized for dual independent amplifiers: pins 1/7 are outputs, pins 2/3 and 5/6 are inverting/noninverting inputs per channel, and pins 4/8 are supplies. It is not pin-compatible with industry-standard dual op-amps like LM358 or TL072. Substitution requires PCB layout revision. Always verify pin functions using the "Pin Functions: TLV2314" table in the SBOS754A datasheet before redesigning around TLV2314IDR.

What is the guaranteed minimum open-loop gain of the TLV2314IDR across temperature and supply voltage?

The TLV2314IDR guarantees a minimum open-loop voltage gain (A_OL) of 85 dB across the full operating range: –40°C to +125°C, 1.8 V to 5.5 V supply, and 0.2 V < V_O < (V+) – 0.2 V. This is explicitly stated in Section 7.7 of the SBOS754A datasheet under "OPEN-LOOP GAIN". At room temperature and 5 V supply, typical performance reaches 115 dB - ensuring stable closed-loop gain accuracy even under worst-case process, voltage, and temperature (PVT) corners.
