SPT232 Datasheet | SPT

Description The 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 pensation. The SPT232, a pin patible enhanced version of the SPT231, reduces 2nd and 3rd harmonic distortion to an extremely low -69d Bc 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 1m V with an input offset drift of 10µV/°C. The SPT232 bines these high performance features with its 0.05% settling time of 15ns and its 100m A drive capability to provide high-speed, high-resolution A/D and D/A converter systems with an attractive solution for driving and buffering. Wide dynamic range systems such as radar and munication receivers 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 transistor technology, and is available in the following versions: SPT232AIH -25°C to +85°C 12-pin TO-8 can SPT232AMH -55°C to +125°C 12-pin TO-8 can, features burn-inand hermetic testing Typical Performance Package Dimensions Features s s s s s s s -69d Bc 2nd and 3rd harmonics at 20MHz -3d B bandwidth of 270MHz 0.005% settling in 15ns 3000V/µs slew rate 1m V input offset voltage, 10µV/°C drift ±10V, 100m A max output Direct replacement for CLC232 Applications s s s s s s s Flash A/D drivers DAC current-to-voltage conversion Wide dynamic range IF amps VCO drivers DDS postamps Radar/munication receivers Precision...
