Product details
Overview
OPA2300AIDGST from Texas Instruments is a dual-channel, high-speed, low-noise CMOS operational amplifier optimized for 16-bit ADC input driving in single-supply systems. It delivers 150MHz gain-bandwidth, 16-bit settling in 150ns, 3nV/√Hz input voltage noise, 0.003% THD+N at 1kHz, and rail-to-rail output swing (V+ −100mV to V− +100mV) on 2.7V–5.5V supplies.
For engineers reviewing the OPA2300AIDGST datasheet, OPA2300AIDGST pinout, OPA2300AIDGST application, or OPA2300AIDGST equivalent, key selection criteria include its dual-channel MSOP-10 package with independent shutdown control per amplifier, 9.5mA quiescent current per channel, and verified performance driving 1.25MSPS 16-bit ADCs like the ADS8401 under 5V single supply.
Technical Context
The OPA2300AIDGST implements a classic two-stage CMOS topology with folded-cascode gain stage and Class AB output stage, enabling unity-gain stability and 80V/µs slew rate. Its digital enable pins (Enable A and Enable B) are referenced to V−, requiring ≥2.5V above V− to activate each amplifier - critical for battery-powered systems needing µA-level shutdown current (5µA per channel).
Designed specifically for high-fidelity signal conditioning before precision ADCs, it supports wide common-mode input range (V− −0.2V to V+ −0.9V), achieves 0.1% settling in 30ns, and maintains >95dB open-loop gain into 2kΩ loads - all specified over −40°C to +125°C industrial temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 150MHz - enables stable closed-loop operation up to ~10MHz with G=10, suitable for IF/RF amplification and active filtering. |
| Input Voltage Noise Density | 3nV/√Hz - ensures minimal added noise when amplifying low-level sensor or preamp signals in 16-bit data acquisition. |
| THD+N @ 1kHz | 0.003% - preserves signal fidelity in audio, instrumentation, and communications applications demanding <−90dB distortion. |
| Quiescent Current per Channel | 9.5mA (typ) at 5.5V - balances speed and power for portable 16-bit systems; drops to 5µA in shutdown mode. |
| Output Voltage Swing | V+ −100mV to V− +100mV (RL ≥2kΩ) - maximizes dynamic range in single-supply 16-bit ADC front-ends without level-shifting circuitry. |
| Settling Time (16-bit) | 150ns - meets timing budget for 1.25MSPS ADCs like ADS8401, ensuring full resolution capture without aperture error. |
| Common-Mode Input Range | V− −0.2V to V+ −0.9V - allows direct interfacing with ground-referenced sensors and DAC outputs in unipolar systems. |
Pinout & Package
OPA2300AIDGST is housed in a 10-pin VSSOP (MSOP-10) package (TI package drawing DGS), measuring 3.05mm × 3.0mm × 1.1mm, RoHS-compliant with NiPdAu lead finish and JEDEC MSL Level-2 rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - V+ | Positive Supply | Accepts 2.7V–5.5V single supply; absolute max 7V - requires local 0.1µF ceramic bypass to ground. |
| 2 - Out B | Channel B Output | High-impedance state during shutdown; drives ADC inputs or active filters directly with rail-to-rail swing. |
| 3 - In− B | Channel B Inverting Input | Differential pair node; ESD-protected with internal diodes clamped to rails - limit input overdrive current to ≤10mA. |
| 4 - In+ B | Channel B Noninverting Input | Ultra-low bias current (±0.1pA typ) enables high-impedance sensor interfaces without significant DC error. |
| 5 - Enable B | Channel B Shutdown Control | CMOS logic input referenced to V−; valid HIGH = V− +2.5V to V+ +0.2V; tON = 5µs, tOFF = 40ns. |
| 6 - Out A | Channel A Output | Independent output with identical AC/DC specs as Out B - supports dual-path signal conditioning or stereo processing. |
| 7 - In− A | Channel A Inverting Input | Matched to In− B for excellent channel-to-channel tracking in differential or composite video applications. |
| 8 - In+ A | Channel A Noninverting Input | Same ultra-low input bias current and CMRR (80dB min) as In+ B - critical for precision differential amplification. |
| 9 - Enable A | Channel A Shutdown Control | Functionally identical to Enable B - enables independent power gating of each amplifier for dynamic power management. |
| 10 - V− | Negative Supply / Ground Reference | Reference for both enable logic and input common-mode range; must be low-impedance for optimal PSRR (200µV/V). |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent shutdown control | Enables per-channel power gating in battery-operated systems, reducing average current to µA levels without PCB redesign. |
| 16-bit settling in 150ns | Guarantees full-resolution sampling for 1.25MSPS ADCs like ADS8401, eliminating need for external settling-time compensation. |
| Rail-to-rail output swing (100mV from rails) | Maximizes usable dynamic range in 5V or 3.3V single-supply data acquisition, avoiding clipping near supply limits. |
| 3nV/√Hz input voltage noise | Preserves SNR in low-amplitude signal chains - e.g., microphone preamps or strain gauge bridges - without degrading 16-bit ENOB. |
| Unity-gain stable with 150MHz GBW | Supports high closed-loop bandwidths (e.g., 15MHz at G=10) without external compensation, simplifying active filter design. |
Applications
| 16-Bit ADC Input Drivers | Low-Noise Preamplifiers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, low-noise op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2301AIDGKT | Single-supply, 150MHz GBW, but only 8-pin MSOP, no per-channel shutdown - shares same core architecture and noise/performance specs. | Lacks independent enable pins; suited for space-constrained dual-op-amp needs where simultaneous on/off is acceptable. | Select OPA2301AIDGKT if board area is critical and dual-channel shutdown is unnecessary; verify layout accommodates shared enable logic. |
| LMH6629MA/NOPB | Higher 1.5GHz GBW and 1000V/µs slew rate, but higher 5.7nV/√Hz noise and 12mA IQ per channel - not unity-gain stable without external compensation. | Better for >50MHz RF gain stages; unsuitable for direct 16-bit ADC driving due to instability risk and increased distortion at lower frequencies. | Choose LMH6629MA/NOPB only for wideband RF amplification beyond 20MHz; avoid for precision ADC buffering where stability and low noise dominate. |
Compared with OPA2301AIDGKT and LMH6629MA/NOPB, the OPA2300AIDGST uniquely combines dual independent shutdown, 150MHz bandwidth, 3nV/√Hz noise, and guaranteed 16-bit settling - making it the only option among the three qualified for battery-powered, high-resolution data acquisition with dynamic power control.

FAQ
What is the maximum supply voltage for the OPA2300AIDGST?
The OPA2300AIDGST has an absolute maximum supply voltage of 7V across V+ to V−. However, its specified operating range is 2.7V to 5.5V. Exceeding 5.5V risks permanent damage and violates the device's qualified electrical specifications - always adhere to the 5.5V upper limit in production designs using OPA2300AIDGST.
Does the OPA2300AIDGST require external compensation for unity-gain stability?
No, the OPA2300AIDGST is internally compensated and unity-gain stable - a key feature confirmed in the datasheet's "Unity-Gain Stable" specification and verified in typical frequency response plots. This eliminates the need for external compensation components when configuring OPA2300AIDGST as a buffer or in low-gain active filters.
How does the enable function work on the OPA2300AIDGST?
The OPA2300AIDGST features two independent CMOS enable inputs (pins 5 and 9), each referenced to V−. A logic HIGH (V− +2.5V to V+ +0.2V) activates the corresponding amplifier; a logic LOW (< V− +0.8V) disables it, reducing quiescent current to 5µA per channel. The OPA2300AIDGST's tON is 5µs and tOFF is 40ns - enabling rapid power cycling in burst-mode systems.
Can the OPA2300AIDGST drive heavy capacitive loads like ADC input capacitance?
The OPA2300AIDGST can drive limited capacitive loads directly, but stability degrades above a few picofarads in unity-gain configuration. For reliable operation into typical ADC input capacitances (e.g., 10–20pF), TI recommends adding a small series resistor (e.g., 10–50Ω) between OPA2300AIDGST's output and the load - as shown in Figure 3 of the datasheet - to isolate the capacitive reactance from the output impedance.
What is the input common-mode voltage range of the OPA2300AIDGST?
The OPA2300AIDGST supports an input common-mode voltage range from (V−) −0.2V to (V+) −0.9V - meaning it accepts inputs slightly below ground (when V− = 0V) and up to 0.9V below the positive rail. This wide range enables direct connection to ground-referenced sources and simplifies biasing in single-supply 16-bit signal chains using OPA2300AIDGST.
