Differential amplifier adc driver

Broadband, Fully-Differential,/Bit ADC DRIVER AMPLIFIER Check for Samples: THS 1FEATURES DESCRIPTION The THS is a fixed-gain of +6dB, wideband, 23• GHz Bandwidth fully-differential amplifier designed and optimized • V/µs Slew Rate, VOUT =2V Step specifically for driving bit analog-to-digital. Analog Devices Single and Fully differential ADC drivers offer precision DC specs and are designed to better reject high frequency PSRR and CMRR through their differential input and output architectures. Analog Devices ADC drivers configured for both precision and high speed differential amps come with a VOCM pin, providing a critical but convenient solution when . Differential amplifiers allow the process of single-ended input to complementary differential outputs or differential inputs to differential outputs. These amplifiers offer low distortion to drive precision and high speed analog-to-digital converters (ADCs). Analog Devices fully differential amplifiers are configured for both precision and high speed and come with a VOCM pin, .

The differential ADC driver has an additional output terminal (V ON) and an additional input terminal (V OCM). These provide great flexibility when interfacing signals to ADCs that have differential inputs. Instead of a single-ended output, the differential ADC driver produces a balanced differential output—with respect to V OCM —between V OP and V ON. Many high performance ADCs are now being designed with differential inputs. A fully differential ADC design offers the advantages of good common-mode rejection, reduction in second-order distortion products, and simplified dc trim algorithms. Although they can be driven single-ended, a fully differential driver usually optimizes overall performance. So next time you need to drive a high-speed, differential-input ADC, be sure to consider an FDA like the LMH or LMH For many applications below 1GHz, the FDA will reduce your bill of materials while providing wider bandwidth support, smaller size, dc-coupling and easier design.

(LNA), ADC driver, channel filter, sampling clock, and ADC stages are shown in Figure 1. fully-differential amplifier can be thought of as two. LMH SE-Input ADC Driver Circuit with A = 6dB. For more information, see LMH GHz Ultra Linear Fully Differential Amplifier. (SNOSB30). Therefore, an implementation of AD chip single to differential amplifier was chosen as an ADC driver to generate sufficient differential output for the.
