pin FuncTions
RCOM (Pin 1): Center Tap Point of RIN and REF. Normally
tied to the negative input of the external reference invert-
ing amplifier.
RIN(Pin2):InputResistorforExternalReferenceInverting
Amplifier. Normally tied to the external reference voltage
VREFandtoROFS(Pin37).Typically5V;acceptsupto±15V.
S2 (Pin 3): Span I/O Bit 2. Pins S0, S1 and S2 are used
to program and to read back the output range of the DAC.
IOUT2 (Pin 4): DAC Current Output Complement. Tie IOUT2
to GND.
NC (Pin 5): No Connection. Must be tied to GND, provides
necessary shielding for IOUT2.
D3-D11(Pins6-14):LTC2751-12 Only.DACInput/Output
Data Bits. These I/O pins set and read back the DAC code.
D11 is the MSB.
D5-D13(Pins6-14):LTC2751-14 Only.DACInput/Output
Data Bits. These I/O pins set and read back the DAC code.
D13 is the MSB.
D7-D15(Pins6-14):LTC2751-16 Only.DACInput/Output
Data Bits. These I/O pins set and read back the DAC code.
D15 is the MSB.
VDD (Pin 15): Positive Supply Input 2.7V ≤ VDD ≤ 5.5V.
Requires a 0.1F bypass capacitor to GND.
GND (Pin 16): Ground. Tie to ground.
CLR (Pin 17): Asynchronous Clear. When CLR is taken
to a logic low, the data registers are reset to the zero-volt
code for the present output range (VOUT = 0V).
MSPAN(Pin18):ManualSpanControlPin.MSPANisused
to configure the LTC2751 for operation in a single, fixed
output range. When configured for single-span operation,
the output range is set via hardware pin strapping. The
span input and DAC registers are transparent and do not
respond to write or update commands.
To configure the part for single-span use, tie MSPAN
directly to VDD. If MSPAN is instead connected to GND
(SoftSpan configuration), the output ranges are set and
verified by using write, update and read operations. See
Manual Span Configuration in the Operation section.
MSPAN must be connected either directly to GND (Soft-
Span configuration) or VDD (single-span configuration).
D0-D2(Pins19-21):LTC2751-12 Only.DACInput/Output
Data Bits. These I/O pins set and read back the DAC code.
D0 is the LSB.
D0-D4(Pins19-23):LTC2751-14 Only.DACInput/Output
Data Bits. These I/O pins set and read back the DAC code.
D0 is the LSB.
D0-D6(Pins19-25):LTC2751-16 Only.DACInput/Output
Data Bits. These I/O pins set and read back the DAC code.
D0 is the LSB.
NC (Pins 22-27): LTC2751-12 Only. No Connection.
NC (Pins 24-27): LTC2751-14 Only. No Connection.
NC (Pins 26, 27): LTC2751-16 Only. No Connection.
D/S (Pin 28): Data/Span Select. This pin is used to select
activation of the data or span I/O pins (D0 to D15 or S0
to S2, respectively), along with their respective dedicated
registers, for write or read operations. Update operations
ignore D/S, since all updates affect both data and span
registers. For single-span operation, tie D/S to GND.
READ(Pin29):ReadPin.WhenREADisassertedhigh,the
data I/O pins (D0-D15) or span I/O pins (S0-S2) output the
contents of the selected register (see Table 1). For single-
span operation, readback of the span I/O pins is disabled.
UPD (Pin 30): Update and Buffer Select Pin. When READ
is held low and UPD is asserted high, the contents of the
input registers (both data and span) are copied into their
respectiveDACregisters.TheoutputoftheDACisupdated,
reflecting the new DAC register values.
When READ is held high, the update function is disabled
and the UPD pin functions as a buffer selector—logic low
to select the input register, high for the DAC register. See
Readback in the Operation section.
WR (Pin 31): Active Low Write Pin. A Write operation
copies the data present on the data or span I/O pins (D0-
D15 or S0-S2, respectively) into the input register. When
READ is high, the Write function is disabled.
S0 (Pin 32): Span I/O Bit 0. Pins S0, S1 and S2 are used
to program and to read back the output range of the DAC.
