High speed operational amplifiers

LINEAR Technology has released two new families of high-speed operational amplifiers, available from Soanar . These devices consume only 50% as much power as competitive devices and deliver low noise performance, rail-to-rail outputs and fully specified 3.3V operation.

The LT6230/1/2 and LT6233/4/5 amplifiers combine features ideal for designing active filters and driving A/D converters in instrumentation, communications and medical equipment.

The LT6233/4/5 are single/dual/quad low noise, rail-to-rail output, unity gain stable op amps that feature 1.9nV/rtHz noise voltage and draw only 1.15mA of supply current per amplifier. These amplifiers combine very low noise and supply current with a 60MHz gain bandwidth product, a 17V/μs slew rate and are optimised for low supply voltage signal conditioning systems. The LT6233-10 is a 375MHz single amplifier optimized for higher gain applications.

The LT6230/1/2 are higher speed versions that offer 215MHz gain bandwidth and an even lower voltage noise of 1.1nV/rtHz, yet still draw 3.4mA of supply current per amplifier. The decompensated version for closed-loop gains greater than 10 (LT6230-10) offers a gain bandwidth product of 1.45GHz and 320V/μs slew rate.

Both families of amplifiers have an output that swings within 50mV of either supply rail to maximise the signal dynamic range in low supply applications. Input offset voltage is trimmed to less than 350μV. The devices are fully specified on 3.3V, 5V and ±5V supplies, and are guaranteed over the commercial and industrial temperature ranges.

The single versions (LT6230/3) offer an enable pin and are available in the 6-lead SOT-23 package. The duals (LT6231/4) are offered in the 8-pin SO package with industry standard pinouts. For compact layouts, the duals are also available in a 3mm x 3mm x 0.8mm dual, flat leadless package (DFN). The quads (LT6232/5) are available in the space-saving 16-pin SSOP package.

R-78xx-0.5 series switching regulator available from Soanar (1-Aug-2008)
Recom, represented in ANZ by Soanar, has released the R-78xx-0.5, a small 7.5 watt switching regulator with up to 97% efficiency. This kind of a situation might exist: a regulated voltage supply is required. In itself, nothing is difficult. Not much board space is available. The input voltage supply is unstabilised and can vary over a wide range. The load is also not exactly steady.
