DESCRIPTION
The ISO809 is a low-power isolated sampling ADC
using state-of-the-art CMOS structures and high volt-
age capacitors. The ISO809 contains a complete 16-bit
capacitor based SAR, ADC with S/H, clock, refer-
ence, µP interface, serial out and galvanic isolation.
Laser-trimmed scaling resistors provide standard
industrial input ranges including ±10V, ±5V, 0-5V,
0-4V. They are available in 28-pin 0.6" wide plastic
DIP and are specified over the industrial temperature
range of –40°C to +85°C.

NOTES: (1) LSB means Least Significant Bit. One LSB for the ±10V input range is 3.05µV. (2) Typical rms noise at worst case transition. (3) As measured with
fixed resistors shown in Figure 7b. Adjustable to zero with external potentiometer. (4) Full scale error is the worst case of –Full Scale or +Full Scale untrimmed
deviation from ideal first and last code transitions, divided by the transition voltage (not divided by the full-scale range) and includes the effect of offset error. (5)
All specifications in dB are referred to a full-scale input. (6) Usable Bandwidth defined as Full-Scale input frequency at which Signal-to-(Noise + Distortion) degrades
to 60dB. (7) Recovers to specified performance after 2 x FS input overvoltage. (8) All devices receive a 1s test. Failure criterion is 5 pulses of 5pC. (9) Tested
at 2500Vrms, 50Hz limit 10µA.

ELECTROSTATIC
DISCHARGE SENSITIVITY
Electrostatic discharge can cause damage ranging from per-
formance degradation to complete device failure. Burr-
Brown Corporation recommends that all integrated circuits
be handled and stored using appropriate ESD protection
methods.
ESD damage can range from subtle performance degrada-
tion to complete device failure. Precision integrated circuits
may be more susceptible to damage because very small
parametric changes could cause the device not to meet
published specifications.
