_________________General Description
The MAX1170 analog-to-digital converter (ADC) is a
12-bit monolithic ADC capable of sample rates greater
than 10Msps. An on-board input buffer and track/hold
function ensure excellent dynamic performance without
the need for external components. A 5pF input capaci-
tance minimizes development problems.
Logic inputs and outputs are TTL compatible. An over-
range output signal is provided to indicate overflow
conditions. Output data format is straight binary. Power
dissipation is a very low 1.1W with power-supply volt-
ages of +5.0V and -5.2V. The MAX1170 also provides a
wide input voltage range of ±2.0V.
The MAX1170 is available in a 32-lead ceramic side-
brazed package and a 44-lead surface-mount CERQUAD
package.
