The OPA300 and OPA301 are unity-gain stable and feature excellent settling and harmonic distortion specifications. Low power applications benefit from low quiescent current. The OPA300 features digital shutdown (Enable) function to provide additional power savings during idle periods. Optimized for single-supply operation, the OPA300 and OPA301 offer superior output swing and excellent commonmode range. The OPA300 and OPA301 have 150MHz of unity-gain bandwidth, low 3nV/√Hz voltage noise, and 0.1% settling within 30ns. Single-supply operation from 2.7V (±1.35V) to 5.5V (±2.75V) and an available shutdown function that reduces supply current to 5µA are useful for portable low-power applications. The OPA300 and OPA301 are available in SO-8 and SOT-23 packages, and are specified over the industrial temperature range of −40°C to +125°C.

Featuring wide 150MHz bandwidth, fast 150nS settling time to 16 bits, and high open loop gain, the OPA300 series offer excellent performance in a small SO-8 and tiny SOT23 packages. PCB LAYOUT As with most high-speed operational amplifiers, board layout requires special attention to maximize AC and DC performance. Extensive use of ground planes, short lead lengths, and high-quality bypass capacitors will minimize leakage that can compromise signal quality. Guard rings applied with potential as near to the input pins as possible help minimize board leakage. INPUT AND ESD PROTECTION THEORY OF OPERATION The OPA30x uses a classic two-stage topology, shown in Figure 1. The differential input pair is biased to maximize slew rate without compromising stability or bandwidth. The folded cascode adds the signal from the input pair and presents a differential signal to the class AB output stage. The class AB output stage allows rail to rail output swing, with high−impedance loads (> 2kΩ), typically 100mV from the supply rails. With 10Ω loads, a useful output swing can be achieved and still maintain high open-loop gain. See the typical characteristic Output Voltage Swing vs Output Current. All OPA30x pins are static protected with internal ESD protection diodes tied to the supplies, as shown in Figure 2. These diodes will provide overdrive protection if the current is externally limited to 10mA, as stated in the Absolute Maximum Ratings. Any input current beyond the Absolute Maximum Ratings, or long-term operation at maximum ratings, will shorten the lifespan of the amplifier. +V External Pin Internal Circuitry +VS −V Figure 2. ESD Protection Diodes VOUT + VIN − VBIAS Figure 1. OPA30x Classic Two-Stage Topology OPERATING VOLTAGE OPA30x op amp parameters are fully specified from +2.7V to +5.5V. Supply voltages higher than 5.5V (absolute maximum) can cause permanent damage to the amplifier. Many specifications apply from –40°C to +125°C. Parameters that vary significantly with operating voltages or temperature are shown in the Typical Characteristics. 10 ENABLE FUNCTION The shutdown function of the OPA300 is referenced to the negative supply voltage of the operational amplifier. A logic level HIGH enables the op amp. A valid logic HIGH is defined as 2.5V above the negative supply applied to the enable pin. A valid logic LOW is defined as < 0.8V above the negative supply pin. If dual or split power supplies are used, care should be taken to ensure logic input signals are properly referred to the negative supply voltage. If this pin is not connected to a valid high to low voltage, the internal circuitry will pull the node high and enable the part to function. The logic input is a high-impedance CMOS input. For battery-operated applications, this feature may be used to greatly reduce the average current and extend battery life. The enable time is 10µs; disable time is 1µs. When disabled, the output assumes a high-impedance state. This allows the OPA300 to be operated as a gated amplifier, or to have its output multiplexed onto a common analog output bus. "## "#$ www.ti.com SBOS271A − MAY 2003 − REVISED DECEMBER 2003 DRIVING CAPACITIVE LOADS DRIVING A 16-BIT ADC When using high−speed operational amplifiers, it is extremely important to consider the effects of capacitive loading on amplifier stability. Capacitive loading will interact with the output impedance of the operational amplifier, and depending on the capacitor value, may significantly decrease the gain bandwidth, as well as introduce peaking. To reduce the effects of capacitive loading and allow for additional capacitive load drive, place a series resistor between the output and the load. This will reduce available bandwidth, but permit stable operation with capacitive loading. Figure 3 illustrates the recommended relationship between the resistor and capacitor values. The OPA30x features excellent THD+noise, even at frequencies greater than 1MHz, with a 16-bit settling time of 150ns. Figure 4 shows a total single supply solution for high-speed data acquisition. The OPA30x directly drives the ADS8401, a 1.25 mega sample per second (MSPS) 16-bit data converter. The OPA30x is configured in an inverting gain of 1, with a 5V single supply. Results of the OPA30x performance are summarized in Table 1. 130pF (mica) 1820Ω fS = 1.25MSPS f = 10kHz 100 5V Series Resistance (Ω) 1820Ω VIN 75 10Ω 130pF (mica) ADS8401 OPA30x 1.5nF 50 25 Figure 4.

The typical characteristic, Frequency Response vs Capacitive Load, describes the relationship between capacitive load and stability for the OPA30x. In unity gain, the OPA300 is capable of driving a few picofarads of capacitive load without compromising stability. Board level parasitic capacitance can often fall into the range of a picofarad or more, and should be minimized through good circuit-board layout practices to avoid compromising the stability of the OPA30x.
