The E1938A may have several variants as at least one of them only uses a single DAC (AD7243AR), presumably for the oven controller. There is an LT1054I nearby, presumably to provide -12V for the DAC Vss supply. The only opamp on the board is an LMC660AIM quad CMOS opamp However readback of the EFC voltage is possible (presumably via the AD7714).
