The LT6658 is ideal for driving the reference input for a high-resolution ADC or DAC using one output, while simultaneously supplying power to other devices using the second output. Both outputs track each other over temperature and load, allowing them to address applications requiring ratiometric supply rails. The outputs have good supply rejection and are stable with up to 50 μF over the entire specified operating range. With this output capability, the LT6658 can serve as both reference and regulator combined. Alternatively the LT6658 can be used to generate a reference plus a virtual ground, or as two matched, tracking references.
The LT6658 is currently available in a 2.5 V version. Options for 1.2 V, 1.8 V, 3 V, 3.3 V and 5 V will be available in the first half of 2017. Prices start at $2.35 each in 1,000-piece quantities.
