TCA440T

Technical Data TCA 440 / T Edition 12/95 AM - Receiver Circuit Description This is an efficient bipolar monolithic circuit to apply in battery - powered or mains - operated radio receivers up to 30 MHz. It contains controlled RF stage, mixer, separated oscillator and regulated multistage IF amplifier. Features symmetrical structured circuitry controlled RF prestage multiplicative balanced mixer, separated oscillator very well implemented large - signal characteristic begins already from 4.5 V supply voltage terminals for indicating instrument controlled IF amplifier implementing 60 dB control range external demodulator (diode) wide range of supply voltage between 4.5 and 15 V Package TCA 440 DIP 16 19.4 ± 0.2 ≤ 1.27 ≤ 1.40 6.4 +0.2 - 0.1 ≤ 5.1 3.5 - 0.5 +1.0 ≥ 0.51 3.6 +0.2 -0.1 ≤ 0.98 2.50 0.47 ±0.12 0.25 M 0.27 -0.07 +0.09 7.55 7.9 . . . 9.7 16 15 14 13 12 11 10 9 1 2 3 4 5 6 7 8 12/95 1 1.35 ± 0.1 TCA 440 T SOP 16 ≤ 2.00 9.9 ± 0.1 6.0 ± 0.2 3.9 ± 0.1 + 0.1 0.05 0...8° 0.15 - 0.15 ≥ 0.3 1.27 0.07 0.42 + - 0.06 ≤ 0.7 0.25 M 16 15 14 13 12 11 10 9 1 2 3 4 5 6 7 8 Pin configuration 1 2 3 4 5 6 7 8 RF prestage, input 1 RF prestage, input 2 RF control amplifier input oscillator circuit pin 1 oscillator circuit pin 2 oscillator circuit pin 3 IF output ground 9 10 11 12 13 14 15 16 input IF control amplifier indicator output IF control amplifier IF blocking input lF amplifier IF blocking supply voltage mi...
