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
29
D5
Parallel Digital Output - bit 5
30
OUT
Output DAC. The bitstream on OUT, when externally filtered, creates a ratiometric analog output volt-
age. 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 V_SS with a 1MΩ (typical) resistor.
48
INM
Negative Sensor Input. Input impedance is typically > 1MΩ. Rail-to-rail input range.
