ADC1206S040/055/070 Single 12 bits ADC, up to 40 MHz, 55 MHz or 70 MHz Rev. 03 2 July 2012 Product data sheet 1. General description The ADC1206S040/055/070 are a family of BiCMOS 12-bit Analog-to-Digital Converters (ADC) optimized for a wide range of applications such as cellular infrastructures, professional telecommunications, imaging, and digital radio. It converts the analog input signal into 12-bit binary coded digital words at a maximum sampling rate of 70 MHz. All static digital inputs (SH, CE and OTC) are Transistor-Transistor Logic (TTL) and CMOS compatible and all outputs are CMOS compatible. A sine wave clock input signal can also be used. 2. Features 12-bit resolution Sampling rate up to 70 MHz 3 dB bandwidth of 245 MHz 5 V power supplies and 3.3 V output power supply Binary or twos complement CMOS outputs In-range CMOS compatible output TTL and CMOS compatible static digital inputs TTL and CMOS compatible digital outputs Differential AC or Positive Emitter-Coupled Logic (PECL) clock input TTL compatible Power dissipation 550 mW (typical) Low analog input capacitance (typical 2 pF), no buffer amplifier required Integrated sample and hold amplifier Differential analog input External amplitude range control Voltage controlled regulator included 40 C to +85 C ambient temperature 3. Applications High-speed analog-to-digital conversion for: Cellular infrastructure Professional telecommunication Digital radio Radar Medical imaging Fixed network Cable modem Integrated Device Technology ADC1206S040/055/070 Single 12 bits ADC, up to 40 MHz, 55 MHz or 70 MHz Barcode scanner Cable Modem Termination System (CMTS)/ Data Over Cable Service Interface Specification (DOCSIS) 4.
