Buffered Outputs, BFB+ and BFB-
BFB+ and BFB- output a buffered version of the voltage
that appears on FB+ and FB-, respectively. The buffers
are typically used in conjunction with the undedicated
chopper amplifier to create a monitor for the thermistor
voltage/TEC temperature (Figures 1 and 2). These
buffers are unity-gain chopper amplifiers and exhibit
output ripple. Each output can be either integrated or
filtered to remove the ripple content if necessary.
Undedicated Chopper-Stabilized Amplifier
In addition to the chopper amplifiers at DIFOUT and
BFB_, the MAX1978/MAX1979 include an additional
chopper amplifier at AOUT. This amplifier is uncommit-
ted but is intended to provide a temperature-propor-
tional analog output. The thermistor voltage typically is
connected to the undedicated chopper amplifier
through the included buffers BFB+ and BFB-. Figure 3
shows how to configure the undedicated amplifier as a
thermistor voltage monitor. The output voltage at AOUT
is not precisely linear, because the thermistor is not lin-
ear. AOUT is also chopper stabilized and exhibits out-
put ripple and can be either integrated or filtered to
remove the ripple content if necessary.
