Linear Technology Corp. (LTC, Milpitas, CA), a manufacturer of high-performance integrated circuits, announced two new families of high-speed operational amplifiers that consume only 50 percent as much power as competitive devices, and deliver ultra-low noise performance, rail-to-rail outputs and fully specified 3.3 V operation. The LT6230/1/2 and LT6233/4/5 amplifiers combine features suitable for designing active filters and driving analog-to-digital converters in instrumentation, communications and medical equipment.
Both families of amplifiers have an output that swings within 50 mV of either supply rail to maximize the signal dynamic range in low supply applications. Input offset voltage is trimmed to less than 350 µV. The devices are fully specified on 3.3 V, 5 V and ±5 V supplies, and are guaranteed over the commercial (0 °C to 70 °C) and industrial (-40 °C to +85 °C) temperature ranges.
The single versions (LT6230/3) offer an enable pin and are available in the six-lead SOT-23 package. The duals (LT6231/4) are offered in the eight-pin SO package with industry-standard pinouts. For compact layouts, the duals are also available in a 3 mm x 3 mm x 0.8 mm, dual, flat, leadless package. The quads (LT6232/5) are available in the 16-pin SSOP package. All versions are now in full production, with pricing from $1.25 in 1,000-piece quantities.
