Application Information

The TQMC701 is a VITA 93.0 compatible single-width

QMC providing 8 channels of simultaneous sampling

single ended or true differential bipolar analog inputs, 4

channels of simultaneous update analog voltage output

and 16 ESD-protected 5 V tolerant TTL digital I/O lines.

The 16 bit analog input channels support per channel

software configurable input modes and voltage ranges.

Each channel can be operated in bipolar single-ended,

unipolar single-ended and bipolar differential mode. In the

single-ended modes it offers software selectable input

voltage ranges of 0-5 V, 0-10 V, 0-12.5 V, ±2.5 V, ±5 V,

±6.25 V, ±10 V and ±12.5 V. In differential mode the input

voltage ranges are selectable between ±5 V, ±10 V,

±12.5 V and ±20 V. Sampling rate for all channels active is

up to 1 Msps.

The 16 bit analog output channels support per channel

software configurable output voltage ranges of 0-5 V, 0

10 V, 0-10.8 V, ±5 V, ±10 V or ±10.8 V. The conversion

time is typ. 10 μs and the DAC outputs are capable to

drive a load of 2 kΩ, with a capacitance of up to 4000 pF.

All 16 digital I/O lines are ESD-protected and 5 V-tolerant.

Every I/O line is individually programmable as input or

output if not used for external synchronization. TTL I/O

lines can be set to high, low, or tristate.
