The HT925x series also supports rail-to-rail input/output voltage ranges. The common mode input range is from VSS+20mV to VDD-20mV and the maximum output voltage is from VSS+35mV to VDD-35mV. In addition, this series of operational amplifiers utilises an advanced CMOS manufacturing process.
The HT925x series consists of the HT9251, which contains a single amplifier in an SOT23-5 package type, the HT9252 which contains dual amplifiers in 8-pin DIP/SOP packages and the HT9254, which contains four amplifiers in 14-pin DIP/SOP packages.
