TDA1048

The TDA1048 is designed as one kind of IF amplifier and AM detector with a total harmonic distortion of 0.001%, and a very high signal-to-noise ratio. The excellent performance of the circuit makes it suitable for data acquisition systems with resolution up to 16 bits. The control input is TTL compatible.

Features of the TDA1048 are:(1)high-speed: fast acquisition, hold-mode setting and aperture time;(2)small sample-to-hold offset step, low droop rate;(3)low noise: low total harmonic distortion and high signal-to-noise ratio;(4)control circuit with TTL input.

The quick reference data of the TDA1048 can be summarized as:(1)supply voltage: 16.5 V;(2)negative supply voltage: -5.5 V to -4.5 V;(3)total harmonic distortion: -100 dB;(4)signal-to-noise ratio: 110 dB;(5)acquisition time to 0.001% (8 V step): 2 us;(6)aperture uncertainty: 0.1 ns;(7)small signal bandwidth: 2 MHz;(8)sample-to-hold offset step: 2 mV;(9)sroop rate: 40 mV/s;(10)hold-mode setting time: 1 us;(11)total power dissipation: 225 mW;(12)operating ambient temperature range: -30 to +85 .
