Analog Devices AD9083 Product Info

The AD9083 is a 16-channel, 125 MHz bandwidth, continuous time Σ-Δ (CTSD) ADC. The device features an on-chip, programmable, single-pole antialiasing filter and termination resistor that is designed for low power, small size, and ease of use.

The 16 ADC cores features a first-order, CTSD modulator architecture with integrated, background nonlinearity correction logic and self cancelling dither. Each ADC features wide bandwidth inputs supporting a variety of user-selectable input ranges. An integrated voltage reference eases design considerations.

The analog input and clock signals are differential inputs. Each ADC has a signal processing tile to filter out of band shaped noise from the Σ-Δ ADC and reduce the sample rate. Each tile contains a cascaded integrator comb (CIC) filter, a quadrature digital downconverter (DDC) with multiple finite input response (FIR) decimation filters (decimate by J block), or up to three quadrature DDC channels with averaging decimation filters for data gating applications.

Users can configure the Subclass 1 JESD204B based, high speed serialized output in a variety of lane configurations (up to four), depending on the DDC configuration and the acceptable lane rate of the receiving logic device. Multiple device synchronization is supported through the SYSREF±, TRIG±, and SYNCINB± input pins.

The AD9083 has flexible power-down options that allow significant power savings when desired. All of these features can be programmed using a 1.8 V capable 3-wire serial port interface (SPI).

The AD9083 is available in a Pb-free, 100-ball CSP_BGA and is specified over the −40°C to +85°C industrial temperature range.
