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 = 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 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.
