The ADC12EU050 12-bit, ultra-low-power, octal CTSD ADC offers an alias-free sample bandwidth up to 25 MHz and a conversion rate of 40 MSPS to 50 MSPS. The device features 68 dB of signal-to-noise and distortion (SINAD) and a signal-to-noise ratio (SNR) of 70 decibels full scale (dBFS). Operating from a 1.2V supply, it consumes 44 mW per channel at 50 MSPS for a total power consumption of only 350 mW. The ADC12EU050 reduces interconnection complexity by using programmable serialized outputs, which offer industry-standard low-voltage differential signaling (LVDS) and scalable low-voltage signaling (SLVS) modes. The ADC12EU050 operates over the -40 degrees C to 85 degrees C temperature range and is supplied in a 10 mm by 10 mm, 68-pin LLP® package.

Key Features

• Lower power dissipation
• Integrated low-pass, brickwall anti-aliasing filter that blocks out-of-band signals from aliasing down in-band, which reduces the signal oversampling required with a pipeline converter
• Easy-to-drive, purely resistive input stage that does not require a sample-and-hold amplifier
• Integrated phase-locked loop (PLL) and voltage-controlled oscillator (VCO) that performs clock conditioning, enabling system designers to use inexpensive clock sources
• On-chip instant-overload recovery (IOR) circuitry that recovers from saturation within one clock cycle, if the input exceeds pre-determined limits
  

Applications

• Battery powered equipment
• Portable medical ultrasound
• Industrial imaging equipment
