[LB1403N Series]

SANYO : SIP9

Use

• AC level meters such as VU meter s.

• DC level meters such as signal meters.

Features and Functions

• Capable of generating a bar -display for input voltage with

5 LEDs.

• Operates from either AC or DC input voltage because of

on-chip rectifier amplifier.

• Lighting levels remain stable to line regulation because

of on-chip voltage reference.

• LEDs are driv en by a constant current ; stable to line re gu-

lation.

• Power supply voltage range is wide (3.5 to 16V), for a

wide range of applications.

• Five types of ICs constitute the series with various light-

ing levels of the LEDs and driving currents.

• SIP-9 pin package and fewer externally connected com-

ponents resuit in smaller space requirements on the cir-

cuit board.

• Low noise at LED lighted mode.

Specifications of any and all SANYO products described or contained herein stipulate the performance,

characteristics, and functions of the described products in the independent state, and are not guarantees

of the performance, characteristics, and functions of the described products as mounted in the customer's

products or equipment. To verify symptoms and states that cannot be evaluated in an independent device,

the customer should always evaluate and test devices mounted in the customer's products or equipment.

SANYO Electric Co., Ltd. strives to supply high-quality high-reliability products. However, any and all

semiconductor products fail with some probability. It is possible that these probabilistic failures could

give rise to accidents or events that could endanger human lives, that could give rise to smoke or fire,

or that could cause damage to other property. When designing equipment, adopt safety measures so

that these kinds of accidents or events cannot occur. Such measures include but are not limited to protective

circuits and error prevention circuits for safe design, redundant design, and structural design.

In the event that any or all SANYO products(including technical data,services) described or

contained herein are controlled under any of applicable local export control laws and regulations,

such products must not be exported without obtaining the export license from the authorities

concerned in accordance with the above law.

·C

1, R1 time constant :

The response time can be varied by varying the C1, R1 time constant (mainly the C1 value).

When the C1, R1 time constant is larger :

..................The response time (attack time and release time) is made slower.

When the C1, R1 time constant is smaller :

..................The response time (attack time and release time) is made faster.

· Considerations relative to Pd max of the package :

Due to the constant current ILED, most of the power consumed by the circuits is consumed within the IC.

When lighting the five LEDs continuously for a prolonged length of time, make sure that VCC does not exceed :

LB1403N, 1413N, 1443N VCC=9V

LB1423N, 1433N VCC=14V

When using a higher power supply voltage, insert a resistor in series with the LEDs to restrain the pow er consumed

within the IC package.

For LB1403N, 1413N, 1443N :

For LB1423N, 1433N
