AD8366ACPZ-R7

AD8366ACPZ-R7 is a DC to 600MHz, dual-digital variable gain amplifier. It is a matched pair of fully differential, low noise and low distortion, digitally programmable variable gain amplifiers (VGAs). This amplifier offers flat frequency performance from DC to 70MHz, independent of gain code. It offers an excellent spurious-free dynamic range, suitable for driving high-resolution analogue-to-digital converters (ADCs). The output common-mode voltage defaults to VPOS/2 but can be programmed via the VCMA and VCMB pins over a range of voltages. The input common-mode voltage also defaults to VPOS/2 but can be driven down to 1.5V. A built-in, dc offset compensation loop can be used to eliminate dc offsets from prior stages in the signal chain. It is used in applications such as baseband I/Q receivers, diversity receivers, and wideband ADC drivers.
