LTM9012 Quad 14-Bit, 125Msps ADC with Integrated Drivers FeaTuresDescripTion n 4-Channel Simultaneous Sampling ADC with The LTM®9012 is a 4-channel, simultaneous sampling Integrated, Fixed Gain, Differential Drivers 14-bit µModule® analog-to-digital converter (ADC) with n 68.3dB SNR integrated, fixed gain, differential ADC drivers. The low n 78dB SFDR noise amplifiers are suitable for single-ended drive and n Low Power: 1.27W Total, 318mW per Channel pulse train signals such as imaging applications. Each n 1.8V ADC Core and 3.3V Analog Input Supply channel includes a lowpass filter between the driver out- n Serial LVDS Outputs: 1 or 2 Bits per Channel put and ADC input. n Shutdown and Nap Modes DC specs include ±1.2LSB INL (typ), ±0.3LSB DNL (typ) n 11.25mm × 15mm BGA Package and no missing codes over temperature. The transition noise is a low 1.2LSBRMS. applicaTions The digital outputs are serial LVDS and each channel out- n Industrial Imaging puts two bits at a time (2-lane mode). At lower sampling n Medical Imaging rates there is a one bit option (1-lane mode). The LVDS n Multichannel Data Acquisition drivers have optional internal termination and adjustable n Nondestructive Testing output levels to ensure clean signal integrity.
