The recommended layout and placement for the LTC2606 involves keeping the analog and digital grounds separate, using a solid ground plane, and placing the device close to the analog signal sources. Additionally, the input and output capacitors should be placed as close as possible to the device pins.
To ensure accurate voltage regulation with the LTC2606, it is essential to use a high-precision voltage reference, such as the LTC6655, and to minimize noise and ripple on the input voltage. Additionally, the output voltage should be filtered using a low-pass filter to reduce noise and improve regulation accuracy.
The maximum output current capability of the LTC2606 is 20mA per channel. However, the device can be paralleled to increase the output current capability, but this requires careful attention to layout and thermal management to avoid overheating.
The output voltage of the LTC2606 can be programmed using a resistive divider network connected to the VREF pin. The resistive divider network sets the output voltage based on the internal reference voltage, and the output voltage can be calculated using the formula provided in the datasheet.
The power-on reset (POR) timing of the LTC2606 is typically around 10ms, but this can vary depending on the input voltage and the output capacitor value. The POR timing can be critical in systems that require a specific power-up sequence, and engineers should consult the datasheet and application notes for more information.
