GENERAL DESCRIPTION
The SPT9404 is a single video line driver chip that takes a standard video signal as an analog input and provides a buffered analog output for driving a 150 load (75 backterminated cable). The standard video input signal (1 VP-P) is typically amplified 6 dB using external components to produce a 2 VP-P into an AC-coupled 150 load. (See the typical interface circuit diagram.) The SPT9404 features a standby mode which draws only 96 W of power. Nominal power dissipation (no input) is typically 32 mW. It requires a single +5 V supply, operates over the commercial temperature range (0 to +70 C) and is available in a tiny surface mount (2.9 x 1.6 mm) 6-lead SOT23 package.

TEST LEVEL CODES
All electrical characteristics are subject to the following conditions: All parameters having min/max specifications are guaranteed. The Test Level column indicates the specific device testing actually performed during production and Quality Assurance inspection. Any blank section in the data column indicates that the specification is not tested at the specified condition.
TEST LEVEL
I II III IV V VI
TEST PROCEDURE
100% production tested at the specified temperature. 100% production tested at TA = +25 C, and sample tested at the specified temperatures. QA sample tested only at the specified temperatures. Parameter is guaranteed (but not tested) by design and characterization data. Parameter is a typical value for information purposes only. 100% production tested at TA = +25 C. Parameter is guaranteed over specified temperature range.

WARNING - LIFE SUPPORT APPLICATIONS POLICY - SPT products should not be used within Life Support Systems without the specific written consent of SPT. A Life Support System is a product or system intended to support or sustain life which, if it fails, can be reasonably expected to result in significant personal injury or death. Signal Processing Technologies believes that ultrasonic cleaning of its products may damage the wire bonding, leading to device failure. It is therefore not recommended, and exposure of a device to such a process will void the product warranty.
