Product details

The AD9691 is a dual, 14-bit, 1.25 GSPSAnalog-to-digital converters(ADC)。 The device includes an on-chip buffer and sample-and-hold circuitry designed for low power, small size, and ease of use. The device is designed for sampling wideband analog signals up to 1.5 GHz.

This dual ADC core uses a multistage, differential pipelined architecture with integrated output error correction logic. Each ADC has wide bandwidth inputs that support a variety of user-selectable input ranges. An integrated reference simplifies design.

Each ADC data output is internally connected to two digital downconverters (DDCs). Each DDC contains four cascaded signal processing stages: a 12-bit frequency converter (NCO) and four half-band decimation filters.

In addition to the DDC block, the AD9691 has additional features that simplify automatic gain control (AGC) in communication receivers. Using the ADC's fast sense output bits, a programmable threshold detector monitors the input signal power. If the input signal level exceeds a programmable threshold, the quick detect indicator goes high. The very low latency of this threshold indicator allows the user to quickly lower the system gain to avoid overrange at the ADC input.

The high-speed serial output of JESD204B Subclass 1 can be set to a variety of single, dual, quad, or octal configurations, depending on the DDC configuration and acceptable lane rate of the receiving logic. SYSREF ± input pins provide multi-device synchronization support.

The AD9691 is available in an 88-lead lead-free LFCSP package and is specified over the industrial temperature range of −40°C to +85°C.
