10 / 20 page  10 LTC1591/LTC1597 15917fa PIN FUNCTIONS LTC1591 REF (Pin 1): Reference Input and 4-Quadrant Resistor R2. Typically ±10V, accepts up to ±25V. In 2-Quadrant mode this is the reference input. In 4-quadrant mode, this pin is driven by external inverting reference amplifier. RCOM (Pin 2): Center Tap Point of the Two 4-Quadrant Resistors R1 and R2. Normally tied to the inverting input of an external amplifier in 4-quadrant operation, otherwise shorted to the REF pin. See Figures 1a and 2a. R1 (Pin 3): 4-Quadrant Resistor R1. In 2-quadrant opera- tion short to the REF pin. In 4-quadrant mode tie to ROFS (Pin 4). ROFS (Pin 4): Bipolar Offset Resistor. Typically swings ±10V, accepts up to ±25V. In 2-quadrant operation tie to RFB. In 4-quadrant operation tie to R1. RFB (Pin 5): Feedback Resistor. Normally tied to the output of the current to voltage converter op amp. Swings to ±VREF. VREF is typically ±10V. IOUT1 (Pin 6): DAC Current Output. Tie to the inverting input of the current to voltage converter op amp. AGND (Pin 7): Analog Ground. Tie to ground. LD (Pin 8): DAC Digital Input Load Control Input. When LD is taken to a logic high, data is loaded from the input register into the DAC register, updating the DAC output. WR (Pin 9):DAC Digital Write Control Input. When WR is taken to a logic low, data is loaded from the digital input pins into the 14-bit wide input register. DB13 to D2 (Pins 10 to 21): Digital Input Data Bits. DGND (Pin 22): Digital Ground. Tie to ground. VCC (Pin 23): The Positive Supply Input. 4.5V ≤ VCC ≥ 5.5V. Requires a bypass capacitor to ground. DB1, DB0 (Pins 24, 25): Digital Input Data Bits. NC (Pins 26, 27): No Connect. CLR (Pin 28):Digital Clear Control Function for the DAC. When CLR is taken to a logic low, it sets the DAC output and all internal registers to zero code for the LTC1591 and midscale code for the LTC1591-1. LTC1597 REF (Pin 1): Reference Input and 4-Quadrant Resistor R2. Typically ±10V, accepts up to ±25V. In 2-Quadrant mode this is the reference input. In 4-quadrant mode, this pin is driven by external inverting reference amplifier. RCOM (Pin 2): Center Tap Point of the Two 4-Quadrant Resistors R1 and R2. Normally tied to the inverting input of an external amplifier in 4-quadrant operation, otherwise shorted to the REF pin. See Figures 1b and 2b. R1 (Pin 3): 4-Quadrant Resistor R1. In 2-quadrant opera- tion short to the REF pin. In 4-quadrant mode tie to ROFS (Pin 4). ROFS (Pin 4): Bipolar Offset Resistor. Typically swings ±10V, accepts up to ±25V. In 2-quadrant operation tie to RFB. In 4-quadrant operation tie to R1. RFB (Pin 5): Feedback Resistor. Normally tied to the output of the current to voltage converter op amp. Swings to ±VREF. VREF is typically ±10V. IOUT1 (Pin 6): DAC Current Output. Tie to the inverting input of the current to voltage converter op amp. AGND (Pin 7): Analog Ground. Tie to ground. LD (Pin 8): DAC Digital Input Load Control Input. When LD is taken to a logic high, data is loaded from the input register into the DAC register, updating the DAC output. WR (Pin 9):DAC Digital Write Control Input. When WR is taken to a logic low, data is loaded from the digital input pins into the 16-bit wide input register. DB15 to D4 (Pins 10 to 21): Digital Input Data Bits. DGND (Pin 22): Digital Ground. Tie to ground. VCC (Pin 23): The Positive Supply Input. 4.5V ≤ VCC ≥ 5.5V. Requires a bypass capacitor to ground. DB3 to DB0 (Pins 24 to 27): Digital Input Data Bits. CLR (Pin 28):Digital Clear Control Function for the DAC. When CLR is taken to a logic low, it sets the DAC output and all internal registers to zero code for the LTC1597 and midscale code for the LTC1597-1. |
