Texas Instruments TLV2362IDGKRG4

Overview

TLV2362IDGKRG4 from Texas Instruments is a dual, low-voltage, rail-to-rail output operational amplifier in an 8-pin VSSOP package. It operates from ±1 V to ±2.5 V supply, delivers 7 MHz unity-gain bandwidth and 3 V/µs slew rate at ±2.5 V, and achieves ±2.4 V output swing into 10 kΩ - enabling high-fidelity signal conditioning in battery-powered audio and sensor interfaces.

For engineers reviewing the TLV2362IDGKRG4 datasheet, TLV2362IDGKRG4 pinout, TLV2362IDGKRG4 application, or TLV2362IDGKRG4 equivalent, key selection criteria include low-voltage operation down to ±1 V, wide output voltage swing, low input offset voltage (≤7.5 mV), low noise (8 nV/√Hz), and thermal performance in the DGK package (θ_JA = 172°C/W).

Technical Context

The TLV2362IDGKRG4 uses a proprietary Texas Instruments bipolar process optimized for low-voltage linearity and dynamic range. Its dual-amplifier architecture supports independent signal paths with matched AC performance across channels, including 7 MHz bandwidth and 3 V/µs slew rate at ±2.5 V supply.

It features rail-to-rail output swing (±2.4 V typ. at ±2.5 V, RL = 10 kΩ), common-mode input voltage range extending to ±1.4 V, and robust ESD protection (±2 kV HBM). The device maintains stable operation under capacitive loads up to 100 pF without external compensation.

FAQ

What is the minimum supply voltage required for TLV2362IDGKRG4 to operate within specifications?

The TLV2362IDGKRG4 is specified to operate with a minimum supply voltage of ±1 V (i.e., total supply span of 2 V). At this level, it maintains functional amplification, though bandwidth and slew rate decrease versus ±2.5 V operation. Full electrical characteristics - including 7 MHz bandwidth and 3 V/µs slew rate - are guaranteed only at ±2.5 V. The TLV2362IDGKRG4 remains fully functional and stable down to ±1 V, making it suitable for single-cell alkaline or NiMH applications where regulated rails are impractical.

Does TLV2362IDGKRG4 support rail-to-rail input voltage range?

No, the TLV2362IDGKRG4 does not feature rail-to-rail input. Its common-mode input voltage range is specified as ±1.4 V maximum over the full −40°C to +85°C temperature range when VCC± = ±2.5 V. This means inputs must remain within 1.4 V of each supply rail - e.g., between −1.1 V and +1.1 V when referenced to ground in a ±2.5 V system. The input stage is bipolar, not CMOS, so it cannot swing to either supply rail. However, its output is rail-to-rail, delivering ±2.4 V into 10 kΩ at ±2.5 V.

Can TLV2362IDGKRG4 drive capacitive loads without oscillation?

Yes, the TLV2362IDGKRG4 is stable driving capacitive loads up to 100 pF when configured with unity gain (AV = 1), as verified in the datasheet's operating characteristics section. For loads exceeding 100 pF - such as long PCB traces or ADC input capacitance - a small series resistor (10–50 Ω) between the output and the load is recommended to maintain phase margin. No external compensation capacitor is required for standard audio or sensor interface loads, simplifying layout in space-constrained VSSOP designs.

What is the thermal resistance (θ_JA) of TLV2362IDGKRG4 in its DGK package?

The junction-to-ambient thermal resistance (θ_JA) for TLV2362IDGKRG4 in the VSSOP-8 (DGK) package is 172°C/W, as stated in the Absolute Maximum Ratings table. This value assumes standard JEDEC test board conditions (2-layer board, 1 in² copper area per side). With typical power dissipation of ~5 mW per amplifier at ±2.5 V (ICC ≈ 2.5 mA/ch), self-heating remains below 1°C - ensuring stable operation even in sealed enclosures at 85°C ambient. No thermal pad soldering is required, though grounding the exposed pad improves θ_JA by ~15°C/W.

Is TLV2362IDGKRG4 pin-compatible with other dual op-amps in the DGK package?

TLV2362IDGKRG4 follows the industry-standard 8-pin VSSOP (DGK) pinout for dual op-amps: Pins 1/8 = outputs, Pins 2/3/6/7 = inputs, Pins 4/5 = supplies. It is pin-compatible with TI's TLV2372IDGKR and OPA2333AIDGKR, as well as generic dual op-amps like MCP6022-E/MS and AD8602ARMZ. However, electrical behavior differs significantly - especially supply range, bandwidth, and input structure - so functional substitution requires validation of gain, stability, and DC accuracy in the target circuit.
