SPT SPT232AIH, SPT232AMH Datasheet

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.

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
