ADS52J90 - 14-Bit, Multichannel, Low-Power, High Speed ADC

The ADS52J90 is a low-power, high-performance, 16-channel,analog-to-digital converter (ADC). The conversion rate of each ADC goes up to a maximum of 100 MSPSin 10-bit mode. The maximum conversionrate reduces when the ADC resolution is set to a higher value.

The device can be configured to accept 8, 16, or 32 inputs. In 32-input mode, each ADCalternately samples and converts two different inputs each at an effective sampling rate that ishalf of the ADC conversion rate. In 8-bit input mode, two ADCs convert the same input in aninterleaved manner, resulting in an effective sampling rate that is twice the ADC conversion rate.The ADC is designed to scale its power with the conversion rate.

The ADC outputs are serialized and output through a low-voltage differential signaling(LVDS) interface along with a frame clock and a high-speed bit clock

The device also has an optional JESD204B interface while operating in the 16-input and32-input modes. This interface runs up to 5 Gbps.

The ADS52J90 is available in a 9-mm × 15-mm, 0.8-mm pitch, NFBGA-198package and is specified over a temperature range of –40°C to +85°C.
