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 THS453x family offers two options: THS4535 (untrimmed) & THS4536 (trimmed).

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 THS4536 provides package level trim for offset and offset drift. THS453x devices also provide higher transient current output drive to meet the needs of successive approximation register (SAR) ADC charge injection and delta-sigma (ΔΣ) ADC precharge buffers.
