MAX121 Datasheet | Maxim Integrated

EVALUATION KIT AVAILABLE 308ksps ADC with DSP Interface and 78dB SINAD General Description The MAX121 is a plete, BiCMOS, serial-output, sampling 14-bit analog-to-digital converter (ADC) that ­bines an on-chip track/hold and a low-drift, lownoise, buried-zener voltage reference with fast conversion speed and low power consumption. The throughput rate is as high as 308k samples per second (ksps). The fullscale analog 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 con­ sumption is only 210mW. The...
