The MAX121CWE+ is a 308Ksps ADC with DSP interface and 78dB SINAD in 16 pin WSOIC package. It is a complete, BiCMOS, serial output, sampling 14bit ADC that combines an on-chip track/hold and a low drift, low noise, buried zener voltage reference with fast conversion speed and low power consumption. The throughput rate is as high as 308Ksps. The fullscale analogue input range is ±5V. The MAX121 utilizes the successive approximation architecture with a high speed DAC to achieve both fast conversion speeds and low-power operation. Operating with +5V and -12V or -15V power supplies, power consumption is only 210mW. The MAX121 can be directly interfaced to the serial port of most popular digital signal processors. The MAX121 operates with TTL and CMOS compatible clocks in the frequency range from 1.1MHz to 5.5MHz. Typical applications include digital signal processing, audio and telecom processing, speech recognition and synthesis, DSP servo control and spectrum analysis.
