I. Device Description
A. General
The MAX5309 is a10-bit, eight channel, low-power, voltage-output, digital-to-analog converters (DAC) in a spacesaving 16-pin TSSOP package. The wide +2.7V to +5.5V supply voltage range and less than 215µA (max) supply
current per DAC is excellent for low-power and low-voltage applications. The low 2nV-s glitch energy of the MAX5309
makes it ideal for digital control of fast-response, closed-loop systems.
The MAX5309 has a hardware reset input (CLR-bar) which clears all registers and DACs to zero. The MAX5309 has
a software shutdown feature that reduces the supply current to 1µA. The MAX5308 features a load DAC (LDAC-bar)
function that updates the output of all eight DACs simultaneously.
The 3-wire SPI™, QSPI™, MICROWIRE™ and DSP-compatible serial interface allows the input and DAC registers
to be updated independently or simultaneously with a single software command. This device uses a double-buffered
design to minimize the digital-noise feedthrough from the digital inputs to the outputs. The MAX5309 operating
temperature range is from -40°C to +85°C

VI. Reliability Evaluation
A. Accelerated Life Test
The results of the 135°C biased (static) life test are shown in Table 1. Using these results, the Failure
Rate (λ) is calculated as follows:
λ=
1
=
MTTF
1.83
192 x 4389 x 79 x 2
(Chi square value for MTTF upper limit)
Temperature Acceleration factor assuming an activation energy of 0.8eV
λ = 13.75 x 10-9
λ = 13.75 F.I.T. (60% confidence level @ 25°C)
This low failure rate represents data collected from Maxim’s reliability monitor program. In addition to
routine production Burn-In, Maxim pulls a sample from every fabrication process three times per week and subjects
it to an extended Burn-In prior to shipment to ensure its reliability. The reliability control level for each lot to be
shipped as standard product is 59 F.I.T. at a 60% confidence level, which equates to 3 failures in an 80 piece
sample. Maxim performs failure analysis on any lot that exceeds this reliability control level. Attached Burn-In
Schematic (Spec. # 06-5814) shows the static Burn-In circuit. Maxim also performs quarterly 1000 hour life test
monitors. This data is published in the Product Reliability Report (RR-1M).
B. Moisture Resistance Tests
Maxim pulls pressure pot samples from every assembly process three times per week. Each lot sample
must meet an LTPD = 20 or less before shipment as standard product. Additionally, the industry standard
85°C/85%RH testing is done per generic device/package family once a quarter.
C. E.S.D. and Latch-Up Testing
The DB06 die type has been found to have all pins able to withstand a transient pulse of ±1500V per MilStd-883 Method 3015 (reference attached ESD Test Circuit). Latch-Up testing has shown that this device
withstands a current of ±250mA.
