| LOW DISTORTION WIDEBAND OP AMP General 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 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 = 100). Additional features provided by the SPT232 include a small signal bandwidth of 270MHz, a large signal bandwidth of 95MHz and a 3000V/s slew rate. The input offset voltage is typically 1mV with an input offset drift of 10V/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 systems with an attractive solution for driving and buffering. Wide dynamic range systems such as radar and communication 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 -25C to +85C 12-pin TO-8 can SPT232AMH -55C to +125C 12-pin TO-8 can, features burn-inand hermetic testing Typical Performance Package Dimensions Features s s s s s s s -69dBc 2nd and 3rd harmonics at 20MHz -3dB bandwidth of 270MHz 0.005% settling in 15ns 3000V/s slew rate 1mV input offset voltage, 10V/C drift 10V, 100mA 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/communication receivers Precision line drivers Bottom View Spectral Response 4755 Forge Road, Colorado Springs, Colorado 80907, USA Phone: (719) 528-2300 FAX: (719) 528-2370 Website: http://www.spt.com E-Mail: sales@spt.com SPT232 Electrical Characteristics (Av = +2, Vcc = 15V, RL = 100, Rf = 250; unless specified) Min/max ratings are based on product characterization and simulation.
