The LTC2498 is a 16-channel (8-differential) 24-bit No Latency ??? ADC with Easy Drive technology. The patented sampling scheme eliminates dynamic input current errors and the shortcomings of on-chip buffering through automatic cancellation of differential input current. This allows large external source impedances, and rail-to-rail input signals to be directly digitized while maintaining exceptional DC accuracy. The LTC2498 includes a high accuracy temperature sensor and an integrated oscillator. This device can be configured to measure an external signal (from combinations of 16 analog input channels operating in single ended or differential modes) or its internal temperature sensor. The integrated temperature sensor offers 1/30th ?C resolution and 2?C absolute accuracy. The LTC2498 allows a wide common mode input range (0V to VCC), independent of the reference voltage. Any combination of single-ended or differential inputs can be selected and the first conversion after a new channel is selected is valid. Access to the multiplexer output enables optional external amplifiers to be shared between all analog inputs and auto calibration continuously removes their associated offset and drift.Applications Direct Sensor Digitizer Direct Temperature Measurement Instrumentation Industrial Process Control

DC1414B-B: Demo Board for the LTM4601AHV 12A, 28VIN DC/DC µModule Regulator with PLL, Output Tracking and Margining.

The LT6604-15 consists of two matched, fully differential amplifiers, each with a 4th order, 15MHz lowpass ?lter. The ?xed frequency lowpass ?lter approximates a Chebyshev response. By integrating a ?lter and a differential amplifier, distortion and noise are made exceptionally low. At unity gain, the measured in band signal-to-noise ratio is an impressive 76dB. At higher gains, the input referred noise decreases, allowing the part to process smaller input differential signals without significantly degrading the signal-to-noise ratio.Gain and phase are highly matched between the two channels. Gain for each channel is independently programmed using two external resistors. The LT6604-15 enables level shifting by providing an adjustable output common mode voltage, making it ideal for directly interfacing to ADCs.The LT6604-15 is fully specified for 3V operation. The differential design enables outstanding performance at a 2VP-P signal level for a single 3V supply.
