4 to 1.
2 V (p-p) to produce a full-scale ADC input of 1 V (p-p) • 3 clamps for programming a clamping code between −63.
5 and +64 in steps of 1⁄2LSB • 3 controllable amplifiers: gain controlled via the serial interface to produce a full scale resolution of 1⁄2LSB peak-to-peak • Amplifier bandwidth of 250 MHz • Low gain variation with temperature • PLL, controllable via the serial interface to generate the ADC clock, which can be locked to a line frequency of 15 to 280 kHz • Integrated PLL divider • Programmable phase clock adjustment cells • Internal voltage regulators • TTL compatible digital inputs and outputs • Chip enable high-impedance ADC output • Power-down mode • Possibility to use up to four ICs in the same system, using the I2C-bus interface, or more, using the 3-wire serial interface • 1.
1 W power dissipation.
APPLICATIONS • R, G and B high-speed digitizing • LCD panels drive • LCD projection systems • VGA and higher resolutions • Using two ICs in parallel, higher display resolution can be obtained; 200 MHz pixel frequency.
ORDERING INFORMATION PACKAGE TYPE NUMBER NAME TDA8752BH/8 QFP100 DESCRIPTION plastic quad flat package; 100 leads (lead length 1.
