DescriptionThe SPT232 is a wideband low distortion operational amplifier designed specifically for high speed, low gain applications requiring wide dynamic range. Utilizing a current feedback architecture, the SPT232 offers high speed performance while maintaining DC precision.
The SPT232 offers precise gains from ±1 to ±5 with a true 0.1% linearity and provides stable, oscillation-free operation across the entire gain range without external compensation. The SPT232, a pin compatible enhanced version of the SPT231, reduces 2nd and 3rd harmonic distortion to an extremely low -69dBc at 20MHz (2Vpp, RL = 100Ω). Additional features provided by the SPT232 include a small signal bandwidth of 270MHz, a large signal bandwidth of 95MHz and a 3000V/µs slew rate. The input offset voltage is typically 1mV with an input offset drift of 10µV/°C.
The SPT232 combines these high performance features with its 0.05% settling time of 15ns and its 100mA drive capability to provide high-speed, high-resolution A/D and D/A converter sys-tems with an attractive solution for driving and buffering.Widedynamic range systems such as radar and communication re-ceivers requiring low harmonic distortion and low noise will find the SPT232 to be an excellent choice. As a linedriver, the SPT232 set at a gain of 2 cancels matched line losses.
The SPT232 is constructed using thin film resistor/bipolar transis-tor technology,and is available in the following versions:SPT232AIH-25 to +85°C 12-pin TO-8 canSPT232AMH -55°C to +125°C 12-pin TO-8 can,features burn-inand hermetic testing
