If you only need one bit, it should be trivial. If you need 14 bits, it's much tougher. The high-resolution parts are generally pipelined devices, so you don't get the output immediately, but only two or three--or more--clocks later. You might have a look at the MAX1449, which Maxim bills as, "World's Lowest-Power 3V, 10-Bit, 105Msps ADC." It's pipelined, and latency is 5.5 clocks, so for low sample rates, you could hit it with a burst of clocks, or else just wait. It appears to allow slow clocking, but beware: typically the pipelined ADCs must hold intermediate values on capacitors. You'd want to clock fast enough to avoid voltage changes on the caps.
