The AD9680 is a dual, 14-bit, 1.25 GSPS/1 GSPS/820 MSPS/500 MSPS analog-to-digital converter (ADC). The device has an on-chip buffer and sample-and-hold circuit designed for low power, small size, and ease of use. This device is designed for sampling wide bandwidth analog signals of up to 2 GHz. The AD9680 is optimized for wide input bandwidth, high sampling rate, excellent linearity, and low power in a small package.The dual ADC cores feature a multistage, differential pipelined architecture with integrated output error correction logic. 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 data output is internally connected to two digital down-converters (DDCs). Each DDC consists of up to five cascaded signal processing stages: a 12-bit frequency translator (NCO), and four half-band decimation filters. The DDCs are bypassed by default.In addition to the DDC blocks, the AD9680 has several functions that simplify the automatic gain control (AGC) function in the communications receiver. The programmable threshold detector allows monitoring of the incoming signal power using the fast detect output bits of the ADC. If the input signal level exceeds the programmable threshold, the fast detect indicator goes high. Because this threshold indicator has low latency, the user can quickly turn down the system gain to avoid an overrange condition at the ADC input.Users can configure the Subclass 1 JESD204B-based high speed serialized output in a variety of one-, two-, or four-lane configurations, depending on the DDC configuration and the acceptable lane rate of the receiving logic device.

The AD7176-2 is a fast settling, highly accurate, high resolution,multiplexed Σ-Δ analog-to-digital converter (ADC) for low bandwidthinput signals. Its inputs can be configured as two fullydifferential or four pseudo differential inputs via the integratedcrosspoint multiplexer. An integrated precision, 2.5 V, low drift(2 ppm/°C), band gap internal reference (with an outputreference buffer) adds functionality and reduces the externalcomponent count.The maximum channel scan data rate is 50 kSPS/channel(settling time of 20 µs), resulting in fully settled data with17 noise free bits. User-selectable output data rates range from5 SPS to 250 kSPS. The resolution increases at lower speeds.The AD7176-2 offers three key digital filters. The fast settlingsinc5 + sinc1 filter maximizes the channel scan rate. The sinc3filter maximizes the resolution for single-channel, low speedapplications. For 50 Hz and 60 Hz environments, the AD7176-2specific filter minimizes the settling times or maximizes therejection of the line frequency. These enhanced filters enablesimultaneous 50 Hz and 60 Hz rejection with a 27 SPS outputdata rate (with a settling time of 36 ms).System offset and gain errors can be corrected on a per channelbasis. This per channel configurability extends to the output datarate used for each channel when using a sinc5 + sinc1 filter.
