Product details
Overview
OPA2300AIDGSR 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. It operates from a single +2.7V to +5.5V supply and features independent digital shutdown (enable) pins per channel - used in high-speed ADC driver and IF amplifier applications.
For engineers reviewing the OPA2300AIDGSR datasheet, OPA2300AIDGSR pinout, OPA2300AIDGSR application, or OPA2300AIDGSR equivalent, key selection criteria include its dual-channel VSSOP-10 package, rail-to-rail output swing (±100mV), shutdown current of 5µA per amplifier, and verified 0.003% THD+N at 1kHz - critical for precision data acquisition and RF signal conditioning.
Technical Context
The OPA2300AIDGSR implements a classic two-stage CMOS topology with folded-cascode gain stage and Class AB output stage, enabling both high slew rate (80V/µs) and unity-gain stability. Its differential input pair is biased for optimal speed-stability tradeoff, supporting 0.1% settling in 90ns and 0.01% in 150ns under 2V step conditions.
Each channel includes a CMOS enable input referenced to V−, with valid logic-high threshold ≥ (V− + 2.5V) and logic-low ≤ (V− + 0.8V). When disabled, the output enters high-impedance state - allowing multiplexed analog bus architectures without external isolation switches.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 150MHz unity-gain bandwidth - supports stable amplification up to UHF frequencies in IF stages. |
| Settling time | 150ns to 16-bit accuracy - ensures full-resolution sampling for 1.25MSPS ADCs like ADS8401. |
| Voltage noise | 3nV/√Hz - preserves SNR in low-amplitude preamplifier and sensor interface chains. |
| THD+N | 0.003% at 1kHz - meets distortion requirements for 16-bit audio and instrumentation signal paths. |
| Supply range | +2.7V to +5.5V single supply - enables direct interfacing with 3.3V and 5V logic/system rails. |
| Shutdown current | 5µA per amplifier - reduces system standby power in battery-powered portable instruments. |
| Output swing | (V+) − 100mV to (V−) + 100mV into 2kΩ - delivers >95% of rail-to-rail dynamic range for maximum ADC utilization. |
Pinout & Package
VSSOP-10 (DGS) package: ultra-thin, surface-mount, 10-pin dual flat no-lead with 0.5mm pitch and exposed thermal pad (not electrically connected). Dimensions: 3.0mm × 3.0mm × 0.9mm (max height).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - V+ | Positive supply rail | Common power input for both amplifiers; must be decoupled locally with 0.1µF ceramic capacitor. |
| 2 - OutB | Channel B output | High-drive, low-impedance output capable of sourcing/sinking 70mA; high-Z when EnableB = low. |
| 3 - −InB | Channel B inverting input | Differential input node with 10¹³Ω || 3pF impedance; ESD-protected via internal diodes to rails. |
| 4 - +InB | Channel B non-inverting input | High-impedance input (±0.1pA bias current); requires guard ring layout for leakage-sensitive applications. |
| 5 - EnableB | Channel B enable control | CMOS input; drives amplifier into low-power shutdown (5µA) when < (V− + 0.8V); high-Z output when disabled. |
| 6 - OutA | Channel A output | Independent output with identical drive capability and shutdown behavior as OutB. |
| 7 - −InA | Channel A inverting input | Matched to −InB; supports fully differential configurations with external feedback networks. |
| 8 - +InA | Channel A non-inverting input | Electrically identical to +InB; enables dual-channel parallel or interleaved signal processing. |
| 9 - EnableA | Channel A enable control | Independent enable logic; allows asymmetric power management (e.g., A active, B shutdown). |
| 10 - V− | Negative supply rail | Reference for both amplifiers and enable thresholds; must be stable and low-impedance. |
Key Features
| Feature | Design Value |
|---|---|
| 16-bit settling in 150ns | Enables full-resolution sampling at ≥6.67 MSPS equivalent effective rate - sufficient for 1.25MSPS 16-bit ADCs with margin. |
| Independent per-channel shutdown | Allows dynamic power scaling in multi-channel systems (e.g., one channel active for monitoring, other in standby). |
| Rail-to-rail output swing (±100mV) | Maximizes usable dynamic range into ADCs with 0–VREF inputs, reducing gain error and quantization loss. |
| Low 3nV/√Hz input voltage noise | Maintains >90dB SNR in 10kHz bandwidth - critical for low-level sensor and medical front-end amplification. |
| Unity-gain stable | Eliminates need for external compensation components in gain = 1 buffer or inverting configurations. |
| Specified over −40°C to +125°C | Validated performance across industrial temperature range - suitable for automotive engine control and base station equipment. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-speed op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2301AIDGKR | No enable function; SOIC-8 or VSSOP-8 package; same 150MHz GBW but higher 12mA quiescent current per channel. | Lacks per-channel shutdown - unsuitable for power-gated systems; better thermal dissipation in SOIC-8 for continuous operation. | Select when always-on dual-channel performance is prioritized over power savings and compact VSSOP-10 footprint. |
| LMH6629MA/NOPB | Higher 1.5GHz GBW, 2.7nV/√Hz noise, but no shutdown; SOIC-8 only; 12.5mA IQ; specified only to +85°C. | Better bandwidth/noise for >100MHz IF stages, but lacks industrial temp range and power control - limits use in automotive or extended-temp designs. | Select when extreme bandwidth dominates requirements and ambient temperature stays ≤85°C. |
Compared with OPA2301AIDGKR and LMH6629MA/NOPB, the OPA2300AIDGSR uniquely combines dual-channel VSSOP-10 packaging, per-amplifier enable, −40°C to +125°C operation, and 150MHz bandwidth with 3nV/√Hz noise - making it the only option meeting all three constraints simultaneously for portable, high-reliability 16-bit data acquisition.

FAQ
What is the maximum capacitive load the OPA2300AIDGSR can drive stably in unity-gain configuration?
The OPA2300AIDGSR is stable driving up to ~5pF of capacitive load in unity-gain configuration without external compensation, as confirmed by Figure 5-16 in the datasheet. For larger loads (e.g., >10pF), a series resistor (RS) between output and load is required - e.g., 30Ω for 47pF or 40Ω for 10pF - to maintain phase margin and prevent peaking. Board parasitics must be minimized through proper layout to avoid unintentional instability.
Does the OPA2300AIDGSR support split-supply operation?
Yes, the OPA2300AIDGSR supports split-supply operation with total supply voltage between +2.7V and +5.5V (e.g., ±2.5V or ±1.35V), provided the absolute voltage on each supply pin remains within Absolute Maximum Ratings (−0.5V to +7V). The enable pins remain referenced to V−, so logic levels must be offset accordingly - e.g., enable ≥ (V− + 2.5V) - even in split-rail setups.
What is the typical output voltage swing of the OPA2300AIDGSR at 5V supply with 2kΩ load?
At VS = 5V and RL = 2kΩ, the OPA2300AIDGSR delivers a typical output swing of (V+) − 100mV to (V−) + 100mV - i.e., 0.1V to 4.9V - as specified in Section 1 Features and Electrical Characteristics Table 5.4. This 4.8Vpp swing provides >96% of full rail-to-rail range, maximizing dynamic headroom for ADC drivers and active filters.
How does the enable function behave during power-up sequencing?
The OPA2300AIDGSR enable pins default to high-impedance pull-up internally, causing both amplifiers to power up enabled unless externally pulled low. To ensure controlled startup, tie EnableA and EnableB to V− through ≤100kΩ resistors if initial shutdown is required. Enable turn-on time is 5µs and turn-off time is 40ns - fast enough for burst-mode signal acquisition but slow enough to avoid supply transients.
Is the OPA2300AIDGSR pin-compatible with other devices in the OPAx30x family?
No, the OPA2300AIDGSR is not pin-compatible with other OPAx30x variants. Its VSSOP-10 (DGS) package contains dedicated enable pins (pins 5 and 9) and separate outputs (pins 2 and 6), unlike the OPA2301AIDGKR (VSSOP-8, no enable) or OPA300AIDBVR (SOT-23-6, single-channel). Pin mapping differs fundamentally across packages - PCB redesign is required for substitution.
