Description
The AX121B-E is a complete, BiCMOS, serial-output, sampling 14-bit analog-to-digital converter (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 308k samples per second (ksps). The full scale analog input range is ±5V.
Specifications and features
The AX121B-E 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. It can be directly interfaced to the serial port of most popular digital-signal processors, and comes in space-saving 16-pin DIP and SO and smaller 20-pin SSOP packages. The AX121B-E operates with TTL- and CMOS-compatible clocks in the frequency range from 1.1MHz to 5.5MHz. All logic inputs and outputs are TTL and CMOS-compatible.
Application Scenarios
The AX121B-E is ideal for applications such as digital signal processing, audio and telecom processing, speech recognition and synthesis, DSP servo control, and spectrum analysis.
Comparison
Advantages: The AX121B-E offers 14-bit resolution, 2.9µs conversion time with a throughput of 308ksps. It has low noise and distortion, with a SINAD of 78d8 and THD of -85dB. The bipolar input range is ±5V, overvoltage tolerant to ±15V. It has a low power dissipation of 210mW and continuous-conversion mode available. The AX121B-E also interfaces with DSP processors and comes in space-saving packages.
Disadvantages: No significant disadvantages identified.
