Binary weighted voltage trim
WebUsing a ladder network is a common way of creating an 8 bit DAC (Digital to Analogue Converter) as each control bit contributes to a binary weighted output voltage. However, for a highly accurate DAC, the resistors will be laser trimmed and located inside a chip. WebDescription The R-2R DAC is one of the most common types of Binary-Weighted DACs. It consists of a parallel binary-weighted resistor bank. Each digital level is converted to an equivalent analog signal by the resistor bank.
