AD9627-125EBZ: 11-Bit, 105/150 MSPS, 1.8 V Dual Analog-to-Digital Converter
The AD9627-11 is a dual 11-bit, 105/150 MSPS analog-to-digital converter (ADC). The AD9627-11 is designed to support communications applications where low cost, small size, and versatility are desired.
The dual ADC core features a multistage, differential pipelined architecture with integrated output error correction logic. Each ADC features wide bandwidth differential sample-and-hold analog input amplifiers supporting a variety of user-selectable input ranges. An integrated voltage reference eases design considerations. A duty cycle stabilizer is provided to compensate for variations in the ADC clock duty cycle, allowing the converters to maintain excellent performance.
The AD9627-11 has several functions that simplify the automatic gain control (AGC) function in the system receiver. The fast detect feature allows fast overrange detection by outputting four bits of input level information with very short latency.
In addition, the programmable threshold detector allows monitoring of the incoming signal power using the four fast detect bits of the ADC with very low latency. If the input signal level exceeds the programmable threshold, the coarse upper threshold indicator goes high. Because this threshold indicator has very low latency, the user can quickly turn down the system gain to avoid an overrange condition.
