MAX1460

Low-Power, 16-Bit Smart ADC

Pin Description (continued)

PIN

NAME

FUNCTION

27

D3

Parallel Digital Output - bit 3

28

D4

Parallel Digital Output - bit 4

28

D5

Parallel Digital Output - bit 5

30

OUT

Output DAC. The bitstream on OUT, when externally filtered, creates a ratiometric analog output

voltage. OUT is proportional to the 12-bit parallel digital output.

33

AMPOUT General-Purpose Operational Amplifier Output

34

AMP+ Noninverting Input of General-Purpose Operational Amplifier

35

AMP- Inverting Input of General-Purpose Operational Amplifier

39

XOUT

Internal Oscillator Output. Connect a 2MHz ceramic resonator (Murata CST200) or crystal from XOUT

to XIN.

40

XIN

Internal Oscillator Input. When TEST is high, this pin must be driven by the test system with a 2MHz,

50% duty cycle clock signal. The resonator does not need to be disconnected in test mode.

46

INP

Positive Sensor Input. Input impedance is typically > 1MΩ. Rail-to-Rail® input range.

47

TEST

Test/Program Mode Enable Input. When high, enables the MAX1460 programming/testing operations.

Internally pulled to VSS with a 1MΩ (typical) resistor.

48

INM

Negative Sensor Input. Input impedance is typically > 1MΩ. Rail-to-rail input range.
