±5V, 1Gsps, 8-Bit ADC with
On-Chip 2.2GHz Track/Hold Amplifier
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 1016 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.

Note 1: Static linearity parameters are computed from a “best-fit” straight line through the code transition points. The full-scale
range (FSR) is defined as 256 · slope of the line.
Note 2: The offset control input is a self-biased voltage divider from the internal +2.5V reference voltage. The nominal open-circuit
voltage is +1.25V. It may be driven from an external potentiometer connected between REFOUT and GNDI.
Note 3: The clock input’s termination voltage can be operated between -2.0V and GNDI. Observe the absolute maximum ratings
on the CLK+ and CLK- inputs.
Note 4: Input logic levels are measured with respect to the VCCO power-supply voltage.
Note 5: All PECL digital outputs are loaded with 50Ω to VCCO - 2.0V. Measurements are made with respect to the VCCO power-
supply voltage.
Note 6: The current in the VCCO power supply does not include the current in the digital output’s emitter followers, which is a func-
tion of the load resistance and the VTT termination voltage.
Note 7: Common-Mode Rejection Ratio is defined as the ratio of the change in the transfer-curve offset voltage to the change in
the common-mode voltage, expressed in dB.
Note 8: Power-Supply Rejection Ratio is defined as the ratio of the change in the transfer-curve offset voltage to the change in
power-supply voltage, expressed in dB.
Note 9: Measured with the positive supplies tied to the same potential; VCCA = VCCD = VCCI. VCC varies from +4.75V to +5.25V.
Note 10: VEE varies from -5.25V to -4.75V.
