  • Product Introduction

Product Details:

The AD9691 is a dual-channel, 14-bit, 1.25 GSPS analog-to-digital converter (ADC). The device has built-in on-chip buffers and sample hold circuitry designed for low power consumption, small size, and ease of use. The device is designed for wideband analog signal sampling up to 1.5 GHz.

This dual-channel ADC core adopts a multi-level, differential pipeline architecture and integrates output error correction logic. Each ADC has a wide bandwidth input that supports a variety of user-selectable input ranges. Integrated voltage reference simplifies design.

Each ADC data output is internally connected to two digital downconverters (DDCs). Each DDC contains 4 cascading signal processing stages: a 12-bit frequency converter (NCO) and four half-band extraction filters.

In addition to the DDC module, the AD9691 has additional features that simplify automatic gain control (AGC) for communication receivers. Using the ADC's fast detection output bit, the programmable threshold detector monitors the input signal power. If the input signal level exceeds the programmable threshold, the quick detection indicator becomes high. Because the threshold indicator has a very low latency, users can quickly adjust down the system gain to avoid over-range at the ADC input.

The high-speed serial outputs of JESD204B subclass 1 can be set to a variety of single, dual, quad, or eight-channel configurations, depending on the DDC configuration of the receiving logic device and the acceptable channel rate. Multi-device synchronization support is provided through SYSREF± input pins.

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