Very Low-power, 12-bit, 20msps Monolithic A/d Convertter

The Comlinear CLC949 is a 12-bit Analog-to-digital converter sub- system including 12-bit quantizer, sample-and-hold Amplifier and internal reference. The CLC949 has been optimized for low power operation with high dynamic range. The CLC949 has a unique feature which allows the user to adjust internal bias levels in the converter which results in a trade-off between power dissipation and maximum conversion rate. With bias set for 220mW power dissipation the converter operates at 20MSPS. Under these conditions, dynamic performance with a 9.9MHz Analog input is typically 68dB SNR and 72dBc SFDR. When bias is set for only 65mW power dissipation the converter maintains excellent perfor- mance at 5MSPS. With a 2.4MHz Analog input signal the SNR is 70dB and SFDR is 78dBc. This excellent dynamic performance in the frequency domain without high power requirements make the part a strong performer for Communications and radar applications. The low input noise of the CLC949 its 0.5LSB differential linearity error specification, fast settling, and low power dissipation also lead to excellent performance in imaging systems. All parts are thoroughly tested to insure that guaranteed specifications are met. The CLC949 incorporates an input sample-and-hold Amplifier followed by a quantizer which uses a pipelined architecture to min- imize Comparator count and the associated power dissipation penalty. An on-board Voltage Reference is provided. Analog input signals, conversion Clock and a single supply are all that are required for CLC949 operation. By National Semiconductor Corporation
