Product specification
1-chip AM radio
TEA5551T
GENERAL DESCRIPTION
The TEA5551T is a 1-chip monolithic integrated radio circuit which is designed for use as a pocket receiver with
headphones in a supply voltage range (V
S
) of 1.8 V to 4.5 V.
The circuit consists of a complete AM part and dual AF amplifier with low quiescent current. The AF part has low radiation
(HF noise) and good overdrive performance. The dual AF amplifier makes the device suitable for operation in an AM/FM
stereo receiver with or without stereo cassette player. The IC has a 1-pin switch for AM or other applications.
Features
Low voltage operation (V
S
= 1.8 V to 4.5 V)
Low current consumption (I
tot
= 5 mA at V
S
= 3 V)
All pins provided with ESD protection
AM part
High sensitivity (V
i
= 1.5
μ
V for V
o
= 10 mV)
Good IF suppression
Good signal handling (V
i(max)
= 80 mV)
Switch for AM or other applications
Short waveband (> 40 MHz)
AF part
A fixed integrated gain of 32 dB
Few external components required
Very low quiescent current
Low HF radiation and good AF overdrive performance
0 to 20 kHz limited frequency response
25 mW per channel output power in 32
