Am79231 Fault Indications
Notes:
1. Unless otherwise specified, test conditions are: VCC = 5 V, RMG1 = RMG2 = 1 k
, BATH =
–
65 V,
BATL = 36 V, VBL = 34, RRX = 150 k
, RL = 600
, RSA = RSB = 200 k
, RFA = RFB = 50
,
CHP = 22 nF, CAD = CBD = 22 nF, IRSN = 84
μ
A. DC-feed conditions are normally set by the ISLAC
device. When the Am79231 is tested by itself, its operating conditions must be simulated as if it were
connected to an ideal ISLAC device.
2. These tests are performed with the following load impedances:
Frequency < 12 kHz
–
Longitudinal impedance = 500
; metallic impedance = 300
Frequency > 12 kHz
–
Longitudinal impedance = 90
; metallic impedance = 135
3. Not tested or partially tested in production. This parameter is guaranteed by characterization or correlation
to other tests.
4. This parameter is tested at 1 kHz in production. Performance at other frequencies is guaranteed by
characterization.
5. When the Am79231 and ISLAC device is in the anti-sat operating region, this parameter is degraded. The
exact degradation depends on system design.
6.
–
55 dBm gain tracking level not tested in production. This parameter is guaranteed by characterization and
correlation to other tests.
7. This spec is valid from 0 V to VBL or
–
50 V, whichever is lower in magnitude.
