six operational amplifiers with two inputs and one output each. The amplifiers can be used in multiple configuration environments ..... PGA modes. Operational amplifiers (OPAMP) 24.1 Introduction The devices embed six operational amplifiers with two inputs and one output each. The three I/Os can be connected to the external pins, thus enabling any type of external interconnections. The operational amplifiers can be configured internally as a follower, as an amplifier with a non-inverting gain ranging from 2 to 64 or with inverting gain ranging from -1 to -63. The positive input can be connected to the internal DAC. The output can be connected to the internal ADC. 24.2 OPAMP main features • Rail-to-rail input and output voltage range • Low input bias current • Low input offset voltage • high frequency gain bandwidth • High-speed mode to achieve a better slew rate ++================================================================ OPAMP modes The operational amplifier inputs and outputs are all accessible on terminals. The amplifiers can be used in multiple configuration environments: • Standalone mode (external gain setting mode) • Follower configuration mode • PGA modes
