I. Device Description
A. General
The MAX9672/MAX9673/MAX9674 output 12/14/16 voltage references for gamma correction in TFT LCDs and one voltage reference for VCOM. Each
gamma reference voltage has its own 10-bit DAC and buffer to ensure a stable voltage. The VCOM reference voltage has its own 10-bit DAC and an
amplifier to ensure a stable voltage when critical levels and patterns are displayed. The MAX9672/MAX9673 MAX9674 feature integrated multiple-time
programmable (MTP) memory to store gamma and VCOM values on the chip, eliminating the need for external EEPROM. The
MAX9672/MAX9673/MAX9674 support up to 300 write operations to the on-chip nonvolatile memory. The gamma outputs can drive 200mA peak
transient current and settle within 1µs. The VCOM output can provide 600mA peak transient current and also settles within 1µs. The analog supply
voltage range extends from 9V to 20V, and the digital supply voltage range extends from 2.7V to 3.6V. Gamma values and the VCOM value are
programmed into registers through the I²C interface.

VI. Reliability Evaluation
A. Accelerated Life Test
The results of the 135C biased (static) life test are shown in Table 1. Using these results, the Failure Rate (
=
1
MTTF
=
1.83
(Chi square value for MTTF upper limit)
192 x 4340 x 48 x 2
(where 4340 = Temperature Acceleration factor assuming an activation energy of 0.8eV)
-9
) is calculated as follows:
= 22.9 x 10
= 22.9 F.I.T. (60% confidence level @ 25°C)
The following failure rate represents data collected from Maxim's reliability monitor program. Maxim performs quarterly life test
monitors on its processes. This data is published in the Reliability Report found at http://www.maxim-ic.com/qa/reliability/monitor.
Cumulative monitor data for the S45 Process results in a FIT Rate of 0.06 @ 25C and 1.00 @ 55C (0.8 eV, 60% UCL)
B. E.S.D. and Latch-Up Testing
The DV26 die type has been found to have all pins able to withstand a transient pulse of:
ESD-HBM:
ESD-CDM:
ESD-MM:
+/- 2500V per JEDEC JESD22-A114 (lot TYXZAQ001E, D/C 0924)
+/- 750V per JEDEC JESD22-C101 (lot TYXZAQ001E, D/C 0924)
+/- 250V per JEDEC JESD22-A115 (lot TYXZAQ001B, D/C 0924)
Latch-Up testing has shown that this device withstands a current of +/- 250mA and overvoltage per JEDEC JESD78 (lot
TYXZAQ001D, D/C 0924).
