The low noise amplifiers are suitable for single-ended drive and pulse train signals such as imaging applications. Each channel includes a lowpass filter between the driver output and ADC input. DC specs include ±1.2LSB INL (typ), ±0.3LSB DNL (typ) and no missing codes over temperature. The transition noise is a low 1.2LSBRMS. The digital outputs are serial LVDS and each channel outputs two bits at a time (2-lane mode). At lower sampling rates there is a one bit option (1-lane mode). The LVDS drivers have optional internal termination and adjustable output levels to ensure clean signal integrity. The ENC+ and ENC- inputs may be driven differentially or single-ended with a sine wave, PECL, LVDS, TTL or CMOS inputs. An internal clock duty cycle stabilizer allows high performance at full speed for a wide range of clock duty cycles. .Data Sheet.net/ Applications n n n n Industrial Imaging Medical Imaging Multichannel Data Acquisition Nondestructive Testing L, LT, LTC, LTM, Linear Technology, the Linear logo and µModule are registered trademarks of Linear Technology Corporation.
