t4U.cGENERAL DESCRIPTION
eThe MP7541B is a pin-compatible replacement which offers
esuperior performance in latch-up and ESD protection versus the
hcomparable 7541 and 7541A. The high ESD protection will re-
duce failures caused by mishandling. These devices are manu-
Sfactured using patented advanced thin film resistors on a double
metal CMOS process which result in ultra stable thin film and su-
taperior long life reliability and stability. The MP7541B incorpo-
rates a bit decoding technique yielding lower glitch, higher
speed and excellent accuracy over temperature and time. The
MP7541B’s outstanding features are:
Stability: Both Integral Non-Linearity (INL) and Differential-
Non-Linearity (DNL) are rated at 0.2 ppm/°C maximum.
Monotonicity is guaranteed over the entire temperature range.
Gain Temperature Coefficient (TCGE) is 2.0 ppm/°C typical.
Lower Sensitivity to Output Amplifier Offset: Multiplying
DACs provide an output current into a virtual ground of the out-
put op amp. Additional linearity error caused by the op amp is
reduced by a factor of 3 in the MP7541B versus conventional
R-2R DACs.
