| FUJITSU SEMICONDUCTOR DATA SHEET DS04-28311-2E ASSP 1CHANNEL 10-BIT D/A CONVERTER MB40760 s DESCRIPTION MB40760 is a low-power consumption, high-speed 10-bit D/A converter. The MB40760 is characterized by TTL compatible digital inputs, an analog output voltage from 3 to 5V, and a maximum conversion rate of 60 MHz. It provides a reference voltage from a potential divider and band-gap reference, and can also use an external reference voltage. The MB40760 D/A converter is suitable for high-resolution TVs or VTRs. s FEATURES * Resolution: 10 bits * Conversion characteristics: Maximum conversion rate: 60 MHz (Minimum) Linearity error: 0.1% (Maximum) Differential linearity error. 0.1% (Maximum) * Input and output: Digital input voltage: TTL levels Analog output voltage: 2 VP-P (3V to 5V) * Reference voltage VROUT1: Potential divider circuit (0.6 VCCA) VROUT2: Band-gap reference circuit (VCCA-2V) * Others Supply voltage: +5V single power supply Power dissipation: 180 mW (Typical value at analog output voltage 2 VP-P) 140 mW (Typical value at analog output voltage 1 VP-P) s PACKAGES Plastic DIP 20 pin , Plastic SOP 20 pin , (DIP-20P-M01) (FPT-20P-M01) MB40760 s PIN ASSIGNMENT (TOP VIEW) (MSB) D1 D2 D3 D4 D5 D6 D7 D8 D9 D10 1 2 3 4 5 6 7 8 9 10 (DIP-20P-M01) (FPT-20P-M01) 20 19 18 17 16 15 14 13 12 11 CLK V CCD VCCA A.OUT V ROUT2 V RIN V ROUT1 COMP A.GND D.GND (LSB) s PIN DESCRIPTIONS Pin No. 1 to 10 20 19 18 11 12 Symbol D1 to D10 CLK VCCD VCCA D.GND A.GND I/O I I -- -- -- -- Clock signal input pin Digital power pin (+5V) Analog power pin (+5 V) Digital ground pin (0V) Analog ground pin (0V) Reference voltage input pin Analog output dynamic range setup pin Connect to pin 14 ot 16 to use the built-in reference voltage When using an external reference voltage, the voltage on this pin must be from 2.7V to 4.3V, and VCCA-VRIN must be from 0.7V to 2.2V Reference voltage output pin 1 The output voltage of the potential divider reference is fixed at 0.6 VCCA.

Preventing Switching Noise To prevent switching noise in the analog output signal, connect noise limiting capacitors to the VCCA and VCCD pins as close to the A.GND and D.GND pins as possible. Power Pattern To reduce parasitic impedance, the PC board pattem to the VCCA, VCCD, A.GND and D.GND pins should be as wide as possible. 2. 9 MB40760 s TYPICAL CHARACTERISTICS CURVES 1.Power Supply Current v.s.
