ESCRIPTIO
The LTC
1409 is a 1
μ
s, 800ksps, sampling 12-bit A/D
converter that draws only 80mW from
±
5V supplies. This
easy-to-use device includes a high dynamic range sample-
and-hold and a precision reference. Two digitally selectable
power Shutdown modes provide flexibility for low power
systems.
The LTC1409 full-scale input range is
±
2.5V. Maximum
DC specs include
±
1LSB INL and
±
1LSB DNL over tem-
perature. Outstanding AC performance includes 72.5dB
S/(N + D) at the Nyquist input frequency of 400kHz.
The unique differential input sample-and-hold can acquire
single-ended or differential input signals up to its 20MHz
bandwidth. The 60dB common mode rejection allows
users to eliminate ground loops and common mode noise
by measuring signals differentially from the source.
The ADC has a
μ
P compatible, 12-bit parallel output port.
There is no pipeline delay in the conversion results.
A separate convert start input and a data ready signal
(BUSY) ease connections to FIFOs, DSPs and micropro-
cessors. A digital output driver power supply pin allows
direct connection to 3V logic.
