I. Device Description
A. General
The MAX2055 high-performance, digitally controlled, variable-gain, differential analog-to-digital converter (ADC)
driver/amplifier (DVGA) is designed for use from 30MHz to 300MHz in base-station receivers.
The device integrates a digitally controlled attenuator and a high-linearity single-ended-to-differential output amplifier,
which can either eliminate an external transformer, or can improve the even-order distortion performance of a
transformer-coupled circuit, thus relaxing the requirements of the anti-alias filter preceding an ADC. Targeted for ADC
driver applications to adjust gain either dynamically or as a one-time channel gain setting, the MAX2055 is ideal for
applications requiring high performance. The attenuator provides 23dB of attenuation range with ±0.2dB accuracy.
The MAX2055 is available in a thermally enhanced 20-pin TSSOP-EP package and operates over the -40°C to +85°C
temperature range.

VI. Reliability Evaluation
A. Accelerated Life Test
The results of the 150°C biased (static) life test are shown in Table 1. Using these results, the Failure Rate
(λ ) is calculated as follows:
λ = 1 = 1.83 (Chi square value for MTTF upper limit)
MTTF 192 x 9823 x 45 x 2
Temperature Acceleration factor assuming an activation energy of 0.8eV
λ = 10.78 x 10-8 λ = 10.78 F.I.T. (60% confidence level @ 25°C)
This low failure rate represents data collected from Maxim’s reliability qualification and monitor programs.
Maxim also performs weekly Burn-In on samples from production to assure reliability of its processes. The reliability
required for lots which receive a burn-in qualification 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 rejects from lots exceeding this level. The Burn-In
Schematic (Spec.# 06-7097) shows the static circuit used for this test. Maxim also performs 1000 hour life test
monitors quarterly for each process. This data is published in the Product Reliability Reports (RR-1M & RR-B3A).
B. Moisture Resistance Tests
Maxim evaluates pressure pot stress from every assembly process during qualification of each new design.
Pressure Pot testing must pass a 20% LTPD for acceptance. Additionally, industry standard 85°C/85%RH or HAST
tests are performed quarterly per device/package family.
C. E.S.D. and Latch-Up Testing
The CR17 die type has been found to have all pins able to withstand a transient pulse of +/-200V, per Mil-Std-
883 Method 3015 (reference attached ESD Test Circuit). Latch-Up testing has shown that this device withstands a
current of ±250mA.
