THS4535数据手册TI中文资料规格书

描述 Description

The THS4535 is a 60MHz fully differential amplifier (FDA) that is specifically designed to drive fully differential analog-to-digital converters (ADCs) up to 2MSPS. The THS4535 family offers multiple options: THS4535 (untrimmed external gain), THS4535A (trimmed external gain), and THS4535Axx (trimmed internal gain).

The THS4535 is an excellent choice for simple single-to-dual conversions. FDAs such as the THS4535 offer performance benefits over traditional dual op amps, including bandwidth and phase balance between outputs and a VOCM pin to easily adjust the output common-mode voltage. For higher dc precision applications, such as high-speed low-side current shunt measurements, the THS4535A provides package level trim for offset and offset drift. THS4535A also provides higher transient current output drive to meet the needs of successive approximation register (SAR) ADC charge injection and delta-sigma (ΔΣ) ADC precharge buffers.

The THS4535Axx, with integrated SiCr resistors, is designed for data acquisition systems (DAQ) that require complete system-level precision. The THS4535Axx integrated resistors are specifically designed to minimize system level gain-error and CMRR over temperature and time. These temperature-stability and long-term-stability performance parameters, along with low signal-to-noise ratio (SNR) and low total harmonic distortion (THD), make the THS4535Axx an excellent choice for DAQ systems.
