The LTC

2290 is a 12-bit 10Msps, low power dual 3V

A/D converter designed for digitizing high frequency, wide

dynamic range signals. The LTC2290 is perfect for

demanding imaging and communications applications

with AC performance that includes 71.3dB SNR and 90dB

SFDR for signals well beyond the Nyquist frequency.

DC specs include

±0.3LSB

INL (typ),

±0.15LSB

DNL (typ)

and no missing codes over temperature. The transition

noise is a low 0.25LSB

RMS

A single 3V supply allows low power operation. A separate

output supply allows the outputs to drive 0.5V to 3.6V

logic. An optional multiplexer allows both channels to

share a digital output bus.

A single-ended CLK input controls converter operation.

An optional clock duty cycle stabilizer allows high perfor-

mance at full speed for a wide range of clock duty cycles.

Note 1:

Stresses beyond those listed under Absolute Maximum Ratings

may cause permanent damage to the device. Exposure to any Absolute

Maximum Rating condition for extended periods may affect device

reliability and lifetime.

Note 2:

All voltage values are with respect to ground with GND and OGND

wired together (unless otherwise noted).

Note 3:

When these pin voltages are taken below GND or above V

, they

will be clamped by internal diodes. This product can handle input currents

of greater than 100mA below GND or above V

Note 5:

Integral nonlinearity is defined as the deviation of a code from a

straight line passing through the actual endpoints of the transfer curve.

The deviation is measured from the center of the quantization band.

Offset error is the offset voltage measured from –0.5 LSB when

the output code flickers between 0000 0000 0000 and 1111 1111 1111.
