LOW OFFSET VOLTAGE DUAL COMPARATOR
USM LM 393
Wide single supply 2.0V to 36V
Dual supplies:±1.0V to ±18V
Very low supply current drain (0.4 mA) independent of supply voltage
In DIE form, this device is an excellent selection for many chip and wire HYBRID CIRCUITS
PRODUCT DESCRIPTION AND SHORT APPLICATION NOTE
The USM LM393 series are dual independent precision voltage comparators capable of single or split power supply operation. These devices are designed to permit a common mode range to ground level with single supply operation.

(NOTE 1)The maximum output current may be as high as 20 mA, independent of the magnitude of VCC, output short circuits to VCC can cause excessive heating and eventual destruction.
(NOTE 2)At output switch point, VO= 1.4 Vdc, RS=0 with VCC from 5.0 Vdc to 30 Vdc, and over the full input common mode range (0 V to V=–1.5 V).
(NOTE 3)Due to the PNP transistor inputs, bias current will flow out of the inputs. This current is essentially constant, independent of the output state, there fore, no loading changes will exist on the input lines.
(NOTE 4)Input common mode of either input should not be permitted to go more than 0.3 V negative of ground or minus supply. The upper limit of common mode range is V CC–1.5 V.
(NOTE 5)5.Response time is specified with a 100 mV step and 5.0 mV of overdrive. With larger magnitudes of overdrive faster response times are obtainable.
(NOTE 6)The comparator will exhibit proper output state if one of the inputs becomes greater than Vrange. The low input state must not be less than –0.3 V of ground or minus supply.
GENERAL DIE INFORMATION
Substrate Thickness (mils) Die size (mils) [mm] Bonding pads(mils) Backside metal
Silicon 10±1 (51.181x47.244) [1.3x1.2] 4.724x4.724 Backside of the die is coated with 0.5µm GOLD , which makes it compatible with AuSi or AuGe die attach.
All US Microwaves products are available in die form. Typical delivery for die products is 2-3 weeks ARO. For Custom designs, delivery is 3-4 weeks ARO. Certain items may be available from stock. Inventory is periodically updated. All devices for chip and wire applications are 100% tested, visual inspected and shipped in waffle packs (WP). For high volume automated assembly, MIS chip capacitors are supplied as 4" wafers 100% tested, inked and diced on expanded film frame (FF).
TECHNOLOGY DESCRIPTION: SEMICONDUCTOR-MANUFACTURING
These integrated Circuits are manufactured with medium voltage junction isolated bipolar process. junction isolated bipolar processes allow integration of high performance NPN, PNP and JFET transistors, MOS capacitors, diffused resistors and precision thin film resistors. The bond pad metallization is standard 1µm Aluminium. The backside of the die is coated with 0.5µm GOLD , which makes it compatible with AuSi or AuGe die attach.
