ADC1206S055

ADC1206S040/055/070 Rev. 02 — 12 August 2008 www.DataSheet4U.com Single 12 bits ADC, up to 40 MHz, 55 MHz or 70 MHz 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.
