device at these or any other conditions above those indicated in the operational

section of this specification is not implied. Exposure to absolute maximum rating

CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily

accumulate on the human body and test equipment and can discharge without detection. Although

the AD8361 features proprietary ESD protection circuitry, permanent damage may occur on

devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are

recommended to avoid performance degradation or loss of functionality.

PIN FUNCTION DESCRIPTIONS

Pin

Micro SOT Name

Description

1

6

VPOS

Supply Voltage Pin. Operational range

2.7 V to 5.5 V.

2

IREF

Output Reference Control Pin. Inter-

nal reference mode enabled when pin

is left open. Otherwise, this pin should

be tied to VPOS. DO NOT ground this

pin.

3

5

RFIN

Signal Input Pin. Must be driven from

an ac-coupled source. The low frequency

real input impedance is 225

Ω.

4

4

PWDN

Power-Down Pin. For the device to

operate as a detector it needs a logical

low input (less than 100 mV). When

is applied, the device is turned off and

the supply current goes to nearly zero

(ground and internal reference mode

less than 1

µA, supply reference mode

Ω).

5

2

COMM Device Ground Pin.

6

3

FLTR

By placing a capacitor between this pin

and VPOS, the corner frequency of the

modulation filter is lowered. The on-

chip filter is formed with 27 pF 2 k

Ω

for small input signals.

7

1

VRMS

Output Pin. Near-rail-to-rail voltage

output with limited current drive capa-

bilities. Expected load >10 k

Ω to ground.

8

SREF

Supply Reference Control Pin. To en-

able supply reference mode this pin

must be connected to VPOS, other-

wise it should be connected to COMM

(ground).
