Product details
Overview
OPA2363AIDGSTG4 from Texas Instruments is a dual-channel, rail-to-rail input/output CMOS operational amplifier optimized for low-voltage, single-supply operation (1.8 V to 5.5 V). It delivers 7 MHz gain-bandwidth, 5 V/µs slew rate, 90 dB typical CMRR, ±10 pA input bias current, and 500 µV maximum input offset voltage - enabling high-fidelity signal conditioning in battery-powered sensor interfaces and portable audio preamplifiers.
For engineers reviewing the OPA2363AIDGSTG4 datasheet, OPA2363AIDGSTG4 pinout, OPA2363AIDGSTG4 application, or OPA2363AIDGSTG4 equivalent, key selection criteria include its dual-channel VSSOP-10 package, shutdown capability per channel, rail-to-rail I/O swing within 10 mV of rails, and guaranteed performance from –40°C to +125°C for industrial-grade embedded systems.
Technical Context
The OPA2363AIDGSTG4 implements a complementary CMOS input stage that eliminates crossover distortion, ensuring monotonic common-mode response and excellent differential linearity when driving SAR or delta-sigma ADCs. Its internal charge-pump topology enables rail-to-rail output swing even at 1.8 V supply without external level-shifting circuitry.
Each amplifier features independent enable control (Enable A on Pin 5, Enable B on Pin 6), allowing dynamic power management in multi-stage analog signal chains. The device is unity-gain stable and specified with 100 pF capacitive load drive capability - supporting direct connection to ADC input filters or RF-sensitive sensor front-ends without oscillation risk.

Pinout & Package
OPA2363AIDGSTG4 is packaged in a 10-pin VSSOP (DGS) with 3.00 mm × 3.00 mm body size, thermally enhanced for high-density layouts and industrial ambient temperatures up to +125°C.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VOUT A | Amplifier A output - drives ADC input, filter network, or next-stage buffer; rail-to-rail swing (within 10 mV of V+ or V−). |
| 2 | –IN A | Inverting input, Channel A - accepts feedback networks for inverting configurations or differential sensing topologies. |
| 3 | +IN A | Noninverting input, Channel A - connects to sensor outputs, reference dividers, or high-impedance signal sources with ≤10 pA bias current. |
| 4 | V− | Negative supply rail - referenced to system ground in single-supply operation; supports true 0-V input common-mode range. |
| 5 | Enable A | Logic-controlled shutdown for Channel A - active-high; pulls output to high-impedance state when low (<0.8 V). |
| 6 | Enable B | Logic-controlled shutdown for Channel B - independent of Channel A; enables asymmetric power sequencing in multi-channel designs. |
| 7 | +IN B | Noninverting input, Channel B - electrically isolated from Channel A inputs; supports dual-sensor or stereo preamp architectures. |
| 8 | –IN B | Inverting input, Channel B - accepts separate feedback components; no crosstalk with Channel A due to >110 dB channel separation at DC. |
| 9 | VOUT B | Amplifier B output - fully independent output stage; capable of sourcing/sinking ±40 mA short-circuit current. |
| 10 | V+ | Positive supply rail - accepts 1.8–5.5 V; internal charge pump ensures rail-to-rail output operation even at minimum supply. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2364AIDR | No shutdown pins; SOIC-8 package; 900 µV max offset; same GBW and CMRR. | Lacks per-channel enable - unsuitable for dynamic power-gating; larger SOIC footprint increases board area. | Select when shutdown is unnecessary and cost or legacy SOIC layout compatibility is prioritized. |
| TLV2462IDR | Lower bandwidth (6.4 MHz); higher offset (1.5 mV max); no shutdown; VSSOP-8 (no Enable pins). | Higher offset degrades 12-bit+ measurement accuracy; no independent enable limits power optimization in battery systems. | Select only for non-critical, cost-sensitive industrial controls where 125°C rating is not required. |

FAQ
What is the maximum supply voltage for OPA2363AIDGSTG4?
The OPA2363AIDGSTG4 supports a maximum supply voltage of 5.5 V across the V+ to V− terminals. Operation above this voltage risks permanent damage, as specified in the Absolute Maximum Ratings table. For reliable long-term use, TI recommends staying within the Recommended Operating Conditions range of 1.8 V to 5.5 V - and the device maintains full rail-to-rail I/O functionality across this entire span. The OPA2363AIDGSTG4 is not rated for split-supply operation beyond ±2.75 V.
Does OPA2363AIDGSTG4 support true rail-to-rail input at 1.8 V supply?
Yes, the OPA2363AIDGSTG4 supports true rail-to-rail input at 1.8 V supply: its input common-mode voltage range extends from (V−) − 0.1 V to (V+) + 0.1 V, meaning it accepts signals from 0 V to 1.9 V when powered from 1.8 V. This is confirmed in Section 7.9 of the datasheet under "INPUT VOLTAGE RANGE". Unlike many older rail-to-rail op amps, the OPA2363AIDGSTG4 achieves this without crossover distortion, preserving linearity near the rails - critical for accurate sensor interfacing.
How does the shutdown function work on OPA2363AIDGSTG4?
The OPA2363AIDGSTG4 features two independent shutdown pins: Enable A (Pin 5) and Enable B (Pin 6). Each pin is active-high: when pulled ≥0.75 × V+, the corresponding amplifier operates normally; when held ≤(V−) + 0.8 V, that channel enters shutdown mode with output in high-impedance state and quiescent current reduced to <1 µA. Both channels can be controlled separately - enabling flexible power sequencing in multi-stage analog signal chains without external logic.
Is OPA2363AIDGSTG4 suitable for driving ADC inputs directly?
Yes, the OPA2363AIDGSTG4 is explicitly designed for direct ADC driving. Its excellent 90 dB CMRR, low 500 µV offset, rail-to-rail output swing (within 10 mV of rails), and absence of phase reversal prevent differential nonlinearity degradation in SAR and sigma-delta ADCs. The datasheet confirms this use case in the Description section and Figure 23 (Typical Application: Single-Supply Microphone Preamplifier), where it drives an ADC input through a simple RC filter - no external buffering required.
What is the thermal resistance (RθJA) of OPA2363AIDGSTG4 in its VSSOP-10 package?
The junction-to-ambient thermal resistance (RθJA) for OPA2363AIDGSTG4 in the DGS (VSSOP-10) package is 166.4°C/W, as specified in Section 7.6 ("Thermal Information: OPA2363") of the official datasheet. This value assumes standard JEDEC 2-layer board conditions. For high-power-density layouts, designers should consider RθJB (junction-to-board) of 86.6°C/W and ψJB of 85.2°C/W to model heat transfer through the PCB copper planes - especially important when operating continuously at +125°C ambient.
