AD9640ABCPZRL7-80

The AD9640ABCPZRL7-80 is an eight channel, 14-bit, 1.8V analog-to-digital converters (ADCs), designed for applications where fast, high-accuracy data conversion is required. The device uses a non-overlapping sampling technique to reduce crosstalk between the separate channels, allowing the signals in each channel to be sampled at up to 1.2 GSPS, making it well-suited for applications such as wideband radio frequency (RF) receivers and software defined radios (SDRs).

Application Field

The AD9640ABCPZRL7-80 can be used in applications such as RF receiver front-ends, wireless transceiver IF sections and synthetic aperture radar (SAR) systems. It is suitable for wideband applications such as SDRs, where high-accuracy and simultaneous sampling of multiple channels are required. The device also offers low power consumption, making it suitable for battery-powered systems.

Working Principle

The AD9640ABCPZRL7-80 is a single-chip, 14-bit, 8-channel ADC that can perform simultaneous sampling on all eight channels. The device uses a non-overlapping sampling technique to minimize crosstalk between the channels so that simultaneous sampling at 1.2 GSPS is possible. The ADC also features an integrated voltage reference for improved performance and can be configured to sample either wideband signals up to 1 GHz or narrowband signals up to 80 MHz.

In addition to its non-overlapping sampling technique, the AD9640ABCPZRL7-80 also utilizes a multi-level sigma-delta architecture to perform the conversion process. This architecture is able to reduce the amount of noise and random errors within the data, resulting in accurate results. Additionally, the device uses a differential analog input topology which helps to improve linearity and reduce harmonic noise.

The AD9640ABCPZRL7-80 also features several other features such as low power consumption and self-calibration capability. Additionally, an output data format of 8-bit gray code mode is available, which can be used to reduce jitter in the data stream.

Conclusion

The AD9640ABCPZRL7-80 is a high-performance, 14-bit, 8-channel analog-to-digital converter designed for applications where fast, accurate data conversion is required. The device uses a non-overlapping sampling technique to reduce crosstalk, allowing the signals in each channel to be sampled at up to 1.2 GSPS. Additionally, the ADC features an integrated voltage reference, low power consumption, and self-calibration capability.
