11 / 23 page www.ti.com DATA FORMAT REGISTERED SELECT BITS DATA BITS: DAC A, DAC B and BUFFER DATA BITS: CONTROL REFERENCE BITS TLV5638 SLAS225C – JUNE 1999 – REVISED JANUARY 2004 APPLICATION INFORMATION (continued) The 16-bit data word for the TLV5638 consists of two parts: • Program bits (D15..D12) • New data (D11..D0) D15 D14 D13 D12 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0 R1 SPD PWR R0 12 Data bits SPD: Speed control bit 1 → fast mode 0 → slow mode PWR: Power control bit 1 → power down 0 → normal operation The following table lists the possible combination of the register select bits: R1 R0 REGISTER 0 0 Write data to DAC B and BUFFER 0 1 Write data to BUFFER 1 0 Write data to DAC A and update DAC B with BUFFER content 1 1 Write data to control register The meaning of the 12 data bits depends on the register. If one of the DAC registers or the BUFFER is selected, then the 12 data bits determine the new DAC value: D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0 New DAC Value If control is selected, then D1, D0 of the 12 data bits are used to program the reference voltage: D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0 X X X X X X X X X X REF1 REF0 REF1 and REF0 determine the reference source and, if internal reference is selected, the reference voltage. REF1 REF0 REFERENCE 0 0 External 0 1 1.024 V 1 0 2.048 V 1 1 External CAUTION: If external reference voltage is applied to the REF pin, external reference MUST be selected. 11 |
