General Description
The MAX104 PECL-compatible, 1Gsps, 8-bit analog-to-
digital converter (ADC) allows accurate digitizing of
analog signals with bandwidths to 2.2GHz. Fabricated
on Maxim’s proprietary advanced GST-2 bipolar
process, the MAX104 integrates a high-performance
track/hold (T/H) amplifier and a quantizer on a single
monolithic die.
The innovative design of the internal T/H, which has an
exceptionally wide 2.2GHz full-power input bandwidth,
results in high performance (greater than 7.5 effective
bits) at the Nyquist frequency. A fully differential com-
parator design and decoding circuitry reduce out-of-
sequence code errors (thermometer bubbles or sparkle
codes) and provide excellent metastable performance
of one error per 10
16 clock cycles. Unlike other ADCs
that can have errors resulting in false full- or zero-scale
outputs, the MAX104 limits the error magnitude to
1LSB.
The analog input is designed for either differential or
single-ended use with a ±250mV input voltage range.
Dual, differential, PECL-compatible output data paths
ensure easy interfacing and include an 8:16 demulti-
plexer feature that reduces output data rates to one-half
the sampling clock rate. The PECL outputs can be
operated from any supply between +3V to +5V for com-
patibility with +3.3V or +5V referenced systems. Control
inputs are provided for interleaving additional MAX104
devices to increase the effective system sampling rate.
The MAX104 is packaged in a 25mm x 25mm, 192-con-
tact Enhanced Super-Ball Grid Array (ESBGA™) and is
specified over the commercial (0°C to +70°C) tempera-
ture range.
