Product details
Overview
OPA2300AIDGSRG4 from Texas Instruments is a dual-channel, low-noise, fast-settling CMOS operational amplifier optimized for 16-bit resolution systems. It delivers 150MHz unity-gain bandwidth, 3nV/√Hz input voltage noise, and 16-bit settling in 150ns, operating from a single +2.7V to +5.5V supply. Its integrated digital shutdown function (5µA per channel) and rail-to-rail output swing (±100mV from rails) make it ideal for high-fidelity ADC front-ends in portable instrumentation.
For engineers reviewing the OPA2300AIDGSRG4 datasheet, OPA2300AIDGSRG4 pinout, OPA2300AIDGSRG4 application, or OPA2300AIDGSRG4 equivalent, key selection criteria include its dual-channel VSSOP-10 package, enable-controlled power gating, 9.5mA quiescent current per amplifier, and guaranteed −40°C to +125°C operation - all critical for precision analog signal chains requiring low distortion and fast transient response.
Technical Context
The OPA2300AIDGSRG4 implements a classic two-stage CMOS topology with folded-cascode gain stage and Class AB output driver, enabling both high slew rate (80V/μs) and unity-gain stability. Its differential input pair is biased for optimal bandwidth-noise trade-off, while internal ESD protection diodes clamp inputs to rails with ±10mA current limit.
It features a CMOS enable input referenced to V−, where logic high (> V− + 2.5V) activates both amplifiers and logic low (< V− + 0.8V) places outputs in high-impedance state with 5µA shutdown current per channel. The device maintains >95dB open-loop gain across −40°C to +125°C and supports capacitive loads up to 100pF with external series resistance for stable unity-gain operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 150MHz unity-gain bandwidth enables accurate amplification of signals up to ~75MHz at G = +2 without significant gain roll-off. |
| Settling Time | 150ns to 16-bit accuracy ensures clean sampling for 1.25MSPS ADCs like ADS8401 without aperture error degradation. |
| Input Voltage Noise | 3nV/√Hz at >1MHz directly limits minimum detectable signal in wideband preamplifier stages. |
| Quiescent Current | 9.5mA per amplifier at 25°C allows battery-powered designs to sustain >10-hour runtime on 100mAh cells with dual-channel active use. |
| Output Swing | V+ − 100mV to V− + 100mV into 2kΩ load preserves dynamic range in single-supply data acquisition systems. |
| Shutdown Current | 5µA per channel reduces system standby power by >99% versus active mode, critical for duty-cycled sensor interfaces. |
| Supply Range | +2.7V to +5.5V single supply eliminates need for negative rail in portable medical or test equipment. |
Pinout & Package
VSSOP-10 (DGS) package: ultra-thin, 3mm × 3mm body, 0.5mm pitch, thermally enhanced with exposed thermal pad (not electrically connected). Compatible with standard SMT reflow profiles (MSL Level-2-260°C-1 year).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5 | No connection | Internally unconnected; must remain floating or grounded per layout best practice to avoid parasitic coupling. |
| 2 | Inverting input B | Differential input node for Channel B; high-impedance CMOS input (10¹³ Ω || 3pF) minimizes loading on preceding stage. |
| 3 | Non-inverting input B | Positive input for Channel B; common-mode range extends to V− − 0.2V and V+ − 0.9V for flexible biasing. |
| 4 | Negative supply (V−) | Ground or negative rail reference; all internal biasing and enable logic referenced to this pin. |
| 6 | Output A | Amplified output of Channel A; capable of sourcing/sinking 70mA short-circuit current with <500mV rail margin into 100Ω. |
| 7 | Non-inverting input A | Positive input for Channel A; identical electrical characteristics to Pin 3, supporting matched dual-channel configurations. |
| 8 | Inverting input A | Inverting input for Channel A; used with Pin 7 for standard op-amp configurations (e.g., inverting gain stage). |
| 9 | Enable A | CMOS-level shutdown control for Channel A; high-impedance input draws <100nA, enabling direct MCU GPIO drive. |
| 10 | Positive supply (V+) | Main power rail; bypass capacitor (≥100nF ceramic) required within 2mm for stable high-frequency operation. |
| Exposed Pad | Thermal pad | Non-electrical thermal slug; must be soldered to PCB copper pour for junction-to-board thermal resistance ≤45°C/W. |
Key Features
| Feature | Design Value |
|---|---|
| 16-bit settling in 150ns | Enables direct interface with 1.25MSPS 16-bit SAR ADCs (e.g., ADS8401) without external sample-and-hold circuitry. |
| 3nV/√Hz input voltage noise | Preserves SNR in low-amplitude sensor signal conditioning paths, such as piezoelectric or MEMS microphone preamps. |
| Dual independent shutdown controls | Allows per-channel power gating in multi-signal-path systems (e.g., simultaneous I/Q channel processing), reducing average system current. |
| Rail-to-rail output swing (±100mV) | Maximizes usable dynamic range in single-supply 3.3V or 5V systems, increasing effective ENOB by ≥0.5 bits vs. legacy rail-swing-limited op-amps. |
| −40°C to +125°C operation | Qualified for under-hood automotive, industrial motor control, and downhole instrumentation where ambient temperature exceeds 105°C. |

FAQ
What is the maximum capacitive load the OPA2300AIDGSRG4 can drive stably in unity-gain configuration?
The OPA2300AIDGSRG4 can drive up to 100pF capacitive load stably in unity-gain configuration when a series resistor (e.g., 20Ω–75Ω depending on CL) is placed between output and load, as verified in Figure 5-16 of the datasheet. Without the resistor, stability is maintained only for ≤5pF, including PCB parasitics.
Does the OPA2300AIDGSRG4 support split-supply operation?
Yes, the OPA2300AIDGSRG4 supports split supplies as long as total voltage remains within +2.7V to +5.5V (e.g., ±2.5V). However, the enable pin is referenced to V−, so logic levels must be offset accordingly - a valid high is > V− + 2.5V, not absolute 2.5V.
What is the typical THD+N performance of the OPA2300AIDGSRG4 at 1MHz?
The OPA2300AIDGSRG4 achieves 0.003% THD+N at 1MHz, VO = 3VPP, G = +1, and VS = 5V, as specified in Section 5.4 Electrical Characteristics. This performance is maintained across the full −40°C to +125°C temperature range.
How does the enable function affect output state during shutdown?
When enabled, the OPA2300AIDGSRG4 operates normally. When disabled (logic low on Enable pin), each amplifier's output enters a high-impedance state - not tri-state in the digital sense, but effectively disconnected from the load, allowing safe multiplexing onto shared analog buses without interaction.
Is the OPA2300AIDGSRG4 pin-compatible with other devices in the OPAx30x family?
No - the OPA2300AIDGSRG4 uses a 10-pin VSSOP (DGS) package with dedicated enable pins for each channel, whereas OPA2301 uses 8-pin SOIC or VSSOP without enable functionality. Pinouts are not interchangeable; PCB layout must match DGS-10 mechanical footprint and signal routing.
